Abstract: Apparatus and methods for control of bandwidth reclamation in a content distribution network. In one embodiment, the invention provides a network operator or subscriber with the ability to disable or otherwise control reclamation in a switched digital video (SDV) network. A controller uses rules in determining whether to reclaim bandwidth. These rules designate certain carriers, content, devices and/or subscribers as high priority (or protected from reclamation). In one variant, the rules determine which subscribers are queried (“pinged”) in order to evaluate whether delivered content is actually being utilized by these subscribers. Alternatively, selected ones of the devices are configured so as to generate an automatic response to any ping messages. In another variant, the rules for disabling bandwidth reclamation are entered via user interaction with an application running on a client device and in communication with the controller via a network proxy, or with the SDV server directly.

Abstract: This invention describes circuits and methods which can allow multiple radar receiver chips to be adjusted to have very low phase offset between them. Multiple receiver chips are used in frequency-modulated carrier-wave (FMCW) radar systems for beamforming to enable angle-of-arrival measurements. FMCW radar systems are widely used in collision-avoidance and adaptive cruise control systems in vehicles, which today are operating in the 76-81 GHz frequency band. In a multi-receiver system, each receive element must have a well-controlled phase response which can be calibrated over process, voltage, and temperature. Without calibration, phase offsets can result in erroneous beamforming receiver measurements. The inventive circuit provides a technique to adjust the phase of multiple receivers across multiple chips using a single local oscillator reference and built-in-test circuitry which consist of phase shifters, a multi-frequency nonlinear phase detection circuit, and power coupling circuits.

Abstract: A phased-array receiver that may be effectively implemented on a silicon substrate. A receiver includes multiple radio frequency (RF) front-ends, each configured to receive a signal with a given delay relative to the others such that the gain of the received signal is highest in a given direction. The receiver also includes a power combination network configured to accept an RF signal from each of the RF front-ends and to pass a combined RF signal to a down-conversion element, where the power distribution network includes a combination of active and passive components. Each RF front-end includes a phase shifter configured to delay the signal in accordance with the given direction and a variable amplifier configured to adjust the gain of the signal.

Abstract: A staged rocket apparatus includes first and second stages connected by a releasable connector. A plurality of pressurized gas struts are connected between the first and second stages and provide a separating force urging the first and second stages apart. The gas struts are held in a telescopingly collapsed first position by the releasable connector. The separating force is maintained at a minimum value so long as the releasable connector holds the struts in their first position. When the releasable connector is disconnected the separating force increases due to gas flow through a metering passage having a progressively increasing flow area from a high pressure chamber to a low pressure chamber.
