Abstract: The present disclosure generally relates to methods for sending event notifications. In some examples, a controller periodically sends messages concerning a status of an event corresponding to the controller. In some examples, at a first time while periodically sending the messages and in accordance with a determination that the status of the event has changed, the controller sends a message concerning data other than the status of the event. In some examples, at the first time while periodically sending the messages and in accordance with a determination that the status of the event has not changed, the controller continues to periodically send the messages without sending the message concerning data other than the status of the event.

For example, a system comprises a dedicated power cell that supplies a power signal and includes a dedicated solar power module that generates electrical energy for the power signal. The system also comprises a dedicated signal conditioner coupled to the power cell and to the radio frequency module, the signal conditioner conditioning the power signal for use by the radio frequency module. The radio frequency module receives conditioned power from the signal conditioner to use in processing a radio frequency signal. The radio frequency module may be a Synthetic Aperture Radar (“SAR”) that comprises one or more radiating elements to transmit pulsed electromagnetic energy for use in radar processing. The SAR may also comprise a receiver that receives the pulsed electromagnetic energy reflected from a target.

Abstract: A system and method for use in obtaining precise positional information relating to one or more points. The points may comprise key locations on a large structure allowing for the geometry of the structure to be assessed based on the positional information. In one embodiment, a high accuracy angular resolution and measurement system includes a laser beam source (110), a bi-directional acousto-optic modulator (112), and an optical detector (104). The position of the optical detector (104) is determinable from deflection angles (120, 122) of the laser beam (106) when the laser beam (106) is deflected by the bi-directional acousto-optic modulator (112) in a direction corresponding to one of a plurality of illumination locations (140) coinciding with the position of the optical detector (104) within an illumination region (142) defined by the illumination locations (140).

Abstract: A passive thermal control system maintains the operating temperature range of protected equipment within desired limits by controlling the conductive attributes of thermal interfaces and physical relationships within the system so as to achieve a desired thermal balance. In one embodiment, an integrated cell unit (100) includes a solar array (102), a Lithium ion cell (108) and an antenna assembly (114) such as a phased array antenna.

Abstract: The power distribution control element significantly improves the efficiency by which solar energy is distributed and controlled to large phased array antenna assemblies by providing current directly from photovoltaic cells to lithium-ion battery cells through a neural-network based charge controller. The small current required to operate each transmit/receive module is provided from an adjacent battery cell rather than a large centralized battery assembly located in the spacecraft bus. In the preferred embodiment, the charge control is regulated by a back-propagation neural network.

A one-piece headrest (10) is formed as a single piece and includes a back mounted support plate (14) having concave central body portion (16) and side wings (17 and 18) which straddle the person's spine to increase comfort, reduce movement of the head rest, and increase stability of the back mounted support plate when attached to the person's upper back. The second embodiment is a two-piece headrest (110) that includes a separate head support portion (120) and a back mounted support plate (114). The head support portion is pivotally connected to the back mounted support plate and a spring (125) urges the head support portion toward the person's head so that support can be provided to the person's head over a continuous angle range of backwardly tilted head positions.

Abstract: A helicopter, or other aircraft, cargo bin is sized and configured so as to closely match the size and configuration of a closed cargo hold in the aircraft. The cargo bin is provided with a cover that is formed from a flame-retardant fabric which can be folded forwardly to open the top of the cargo bin, whereby the open bin can be positioned on a hydraulic ramp in the cargo hold before or after the bin is filled with cargo. The bin also has a hinged back wall which can be partially folded downwardly so as to open the upper portion of the back wall while keeping the lower portion of the back wall closed. This allows luggage or the like to be placed in the bin, when the bin is in the cargo hold, through the upper open portion of the bin, while enabling the lower closed portion of the bin to prevent the inserted luggage from sliding out of the bin.
