Author Mary Elise Antoine discusses five Black women illegally enslaved in the early 1800s whose lives and fates all intersected in the Upper Mississippi River Valley. The Wisconsin Historical Society hosts this event.
LG G3 live event feed
The Motorola Shamu, believed to be the upcoming Nexus 6 smarptohne, is starring in a live photo with the LG G3. The phone looks substantially larger than the G3, which carries a 5.5" display. This lends further credence to rumors that the Shamu is going to feature a display in the 6" ballpark.
The battery of the Shamu is allegedly a 3,200mAh unit. As with all recent Nexus smartphones, don't expect a microSD card slot. The Shamu should be unveiled at Google's Android L release event and will run it out of the box.
Working with both existing partners and future partners to come, DAZN will offer select mega fights as Pay Per View add-on events. These occasional Pay Per View fights will be available to both existing and new DAZN subscribers in selected countries, live and on demand.
New customers who purchase the PPV will then be able to enjoy a host of other content as part of their included subscription, which includes more live boxing, a variety of other live sports (depending on your country, check DAZN.com for more information), exclusive interviews with top fighters, regular episodes of The DAZN Boxing Show and The DAZN Soccer Show, topnotch documentaries such as The Making Of Canelo and more.
The Canelo-Golovkin 3 card will stream live on DAZN in across the globe, except in Mexico, Kazakhstan, Latin America (Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, Panama, Colombia, Venezuela, Ecuador, Peru, Bolivia, Brazil, Paraguay, Chile, Argentina, Uruguay, Cuba, Haiti, Dominican Republic). You can sign up for a subscription here.
Bargains are a big part of the Wyze brand, and the Wyze Cam Outdoor is no different. It records video in Full HD with a 110-degree field of view and comes with a base station that plugs into your router for setup but can connect wirelessly thereafter. This base station takes a MicroSD card (not included) for local video recording, and I strongly recommend utilizing this. Otherwise, there's a 12-second limit for video clips and a five-minute cooldown in between motion events if you store everything in the cloud (accessible for 14 days). If you prefer the cloud, you can pay $24 per year for unlimited video length and no cooldowns, along with other perks like person detection. The stated battery life is between three and six months, but mine needed a charge before it reached three.
You need a Google account and the Google Home app to use it. You don't need the $6 per month Nest Aware subscription, but most people buying Google devices are probably not afraid of storing data on the cloud or of machine learning. It's worth it to have features like the camera's ability to learn faces and 60-day event history, and even more so if you're bundling it with your Nest Doorbell. The battery needs charging after a little more than a month.
There are some big caveats to this Logitech security camera. First, it has a permanently attached 10-foot power cord that's not weather-proof, so you'll need to be careful when you route it to an indoor outlet. It also requires a HomeKit hub, such as HomePod Mini, Apple TV, or iPad, and while you can record 10 days of video events to your iCloud account, it's only worthwhile if you cough up for an iCloud storage plan. There's also zero compatibility with Android, so it might be useless for anyone in the household without an Apple gadget.
Blurams Outdoor Lite 3 for $65: This is a feature-packed security camera for the price, with support for pan, tilt, and zoom functionality, spotlights, siren, motion tracking, continuous recording, and two-way audio. You can store footage locally on a microSD card (sold separately) or subscribe to a cloud plan. Video quality is reasonable, but the app is very glitchy and loading the live feed was inconsistent (sometimes it just buffered indefinitely).
Satellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location.[1] The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter.
The downlink satellite signal, quite weak after traveling the great distance (see path loss), is collected with a parabolic receiving dish, which reflects the weak signal to the dish's focal point.[11] Mounted on brackets at the dish's focal point is a device called a feedhorn or collector.[12] The feedhorn is a section of waveguide with a flared front-end that gathers the signals at or near the focal point and conducts them to a probe or pickup connected to a low-noise block downconverter (LNB).[13] The LNB amplifies the signals and downconverts them to a lower block of intermediate frequencies (IF), usually in the L-band.[13]
The original C-band satellite television systems used a low-noise amplifier (LNA) connected to the feedhorn at the focal point of the dish.[14] The amplified signal, still at the higher microwave frequencies, had to be fed via very expensive low-loss 50-ohm impedance gas filled hardline coaxial cable with relatively complex N-connectors to an indoor receiver or, in other designs, a downconverter (a mixer and a voltage-tuned oscillator with some filter circuitry) for downconversion to an intermediate frequency.[14] The channel selection was controlled typically by a voltage tuned oscillator with the tuning voltage being fed via a separate cable to the headend, but this design evolved.[14]
The downlinked satellite signal, weaker after traveling the great distance (see path loss), is collected by using a rooftop parabolic receiving dish ("satellite dish"), which reflects the weak signal to the dish's focal point.[21] Mounted on brackets at the dish's focal point is a feedhorn[21] which passes the signals through a waveguide to a device called a low-noise block converter (LNB) or low noise converter (LNC) attached to the horn.[21] The LNB amplifies the weak signals, filters the block of frequencies in which the satellite television signals are transmitted, and converts the block of frequencies to a lower frequency range in the L-band range.[21] The signal is then passed through a coaxial cable into the residence to the satellite television receiver, a set-top box next to the television.
An event called sun outage occurs when the sun lines up directly behind the satellite in the field of view of the receiving satellite dish.[23] This happens for about a 10-minute period daily around midday, twice every year for a two-week period in the spring and fall around the equinox. During this period, the sun is within the main lobe of the dish's reception pattern, so the strong microwave noise emitted by the sun on the same frequencies used by the satellite's transponders drowns out reception.[23]
Direct-to-home (DTH) can either refer to the communications satellites themselves that deliver service or the actual television service. Most satellite television customers in developed television markets get their programming through a direct broadcast satellite (DBS) provider.[24] Signals are transmitted using Ku band (12 to 18 GHz) and are completely digital which means it has high picture and stereo sound quality.[2]
Programming for satellite television channels comes from multiple sources and may include live studio feeds.[25] The broadcast center assembles and packages programming into channels for transmission and, where necessary, encrypts the channels. The signal is then sent to the uplink[26] where it is transmitted to the satellite. With some broadcast centers, the studios, administration and up-link are all part of the same campus.[27] The satellite then translates and broadcasts the channels.[28]
TVRO systems were designed to receive analog and digital satellite feeds of both television or audio from both C-band and Ku-band transponders on FSS-type satellites.[35][36] The higher frequency Ku-band systems tend to resemble DBS systems and can use a smaller dish antenna because of the higher power transmissions and greater antenna gain. TVRO systems tend to use larger rather than smaller satellite dish antennas, since it is more likely that the owner of a TVRO system would have a C-band-only setup rather than a Ku band-only setup. Additional receiver boxes allow for different types of digital satellite signal reception, such as DVB/MPEG-2 and 4DTV.
The world's first commercial communications satellite, called Intelsat I and nicknamed "Early Bird", was launched into geosynchronous orbit on April 6, 1965.[46] The first national network of television satellites, called Orbita, was created by the Soviet Union in October 1967, and was based on the principle of using the highly elliptical Molniya satellite for rebroadcasting and delivering of television signals to ground downlink stations.[47] The first commercial North American satellite to carry television transmissions was Canada's geostationary Anik 1, which was launched on 9 November 1972.[48] ATS-6, the world's first experimental educational and direct broadcast satellite (DBS), was launched on 30 May 1974.[49] It transmitted at 860 MHz using wideband FM modulation and had two sound channels. The transmissions were focused on the Indian subcontinent but experimenters were able to receive the signal in Western Europe using home constructed equipment that drew on UHF television design techniques already in use.[50]
The satellite television industry developed first in the US from the cable television industry as communication satellites were being used to distribute television programming to remote cable television headends. Home Box Office (HBO), Turner Broadcasting System (TBS), and Christian Broadcasting Network (CBN, later The Family Channel) were among the first to use satellite television to deliver programming. Taylor Howard of San Andreas, California, became the first person to receive C-band satellite signals with his home-built system in 1976.[53] 2ff7e9595c
