  • Patent number: 8699502
    Abstract: A media receiver hub receives wireless signals from multiple sources (e.g., satellite signals from multiple satellites) and provides the signals to end devices over a local network. According to an example embodiment, a satellite hub is responsive to channel input selections received from end devices by selecting channels from within received satellite signals, and by converting each channel into a format amenable for delivery to and use at an end device requesting the channel. The converted channels are communicated to the end devices over a network that also facilitates communications between the devices, by restricting the communications to using a portion of the available bandwidth of the network, reserving bandwidth for communications with and/or between the end devices (or other network devices).

  • Patent number: 8107914
    Abstract: Radio-frequency (RF) circuits, methods and systems are implemented according to a variety of embodiments. According to one such embodiment, a radio-frequency (RF) receiver circuit is implemented with an adjustable RF filter circuit in a receive path of the RF receiver circuit. A local oscillator (LO) generates a LO signal and an RX_LO signal from the LO signal. A mixing circuit mixes a signal received from the adjustable RF filter circuit and the RX_LO signal. An intermediate-frequency (IF) circuit generates an IF_cal signal at the receiver circuit. A calibration circuit implements both a calibration mode and a receive mode. In the calibration mode, a calibration signal is injected into the receive path. A setting of the adjustable RF filter circuit is determined. In the receive mode, the calibration circuit disables the injection of the calibration signal into the receive path of the RF receiver circuit.

  • Publication number: 20110219416
    Abstract: Effects of a network delay in handling messages in time-shifting media information streams are eliminated by either the network side's providing a media stream start time to the client side, which uses the media start time to compute a correct time offset for restarting the media stream after a pause, or by the client side's providing the time of a pause request to the network side, which uses the pause request time to compute the correct time offset and provides the offset to the client side.

  • Publication number: 20080047188
    Abstract: The invention is a height adjustable gun rest that can be attached, and carried folded, on a rifle's fore-end. Known gun rests are in particular unsuitable on snow, and therefore unsuitable for grouse top-hunting for instance. Loud or awkward folding, or unsuitable exterior form (for carrying the rifle on the back), are other problems relevant to this kind of hunting. The invention includes a supporting leg 1, a bearing plate 2, and a pivot catch 3. The fore-end 101 can be imagined as the upper horizontal bar of a “Z” where the supporting leg, pivoted to the fore-end, is the inclined line and the bearing plate, pivoted to the supporting leg, is the lower horizontal bar. This arrangement facilitates compact and simple folding. The bearing plate provides large contact surface. The pivot catch fix the leg's inclination angle; that is, one of the angles of the “Z” is constant while the other is variable.
