摘要： Apparatus and associated methods relate to providing robust synchronization of a Radio-Frequency (RF) communication in a severe-fading environment. A first portion of a detected RF signal is auto-correlated with a second portion of the detected RF signal. The first and second portions are time-separated by the predetermined time delay separating the first and second code-sequences. A third portion of the detected RF signal is sync-correlated with a sync-sequence so as to generate a sync-correlation signal. The third portion is of the predetermined length of the sync sequence and includes the first and second portions of the detected RF signal used to generate the auto-correlation signal. The auto-correlation signal is multiplied by the sync-correlation signal so as to generate a combined synchronization signal. A peak in the combined synchronization signal is then detected. This peak can be indicative of a synchronization time of an authorized communication.

摘要： A build of a software solution that is cooperatively performed is automated. A broadcasting computing entity selects a selected set of functional operations from one or more sets of functional operations associated with the software solution and then broadcasts a request to perform each of the functional operations in the selected set. Each of a plurality of listening computing entities connected to the network receives the request and determines capability of performing each of the functional operations in the selected set. After determining itself capable, a capable one of the plurality of listening computing entities transmits a response to the request indicating such capability, and then performs each of the functional operations in the selected set, thereby generating and transmitting to the broadcasting computing entity the output of the selected set of functional operations. The broadcasting computing entity then performs an action using the output of the functional operation received.

摘要： A method for making a ceramic matrix composite component includes densifying a fibrous preform of the component with a ceramic matrix to form an intermediate component; infiltrating a hole in the intermediate component with an infiltrate material comprising a solid and a metallic alloy whose reaction forms a carbide, silicide, boride or combination thereof, heating the infiltrate material to a temperature in excess of a melting point of the metallic alloy; and sequentially cooling regions of the hole starting from an interior end of the hole to the outer surface of the intermediate component to form a solidified through-thickness reinforcement element. The hole extends in a through-thickness direction and is open to an exterior surface of the intermediate component.

摘要： A vehicle lubrication system includes a plurality of sensors disposed on the vehicle and configured to sense operational characteristics of the vehicle, a pump disposed on the vehicle and configured to deliver lubricant to a plurality of lubricated regions of the vehicle, and a controller device operatively coupled to the pump. The controller device is configured to receive sensor data corresponding to the operational characteristics of the vehicle sensed by the plurality of sensors, and determine, based on the received sensor data, a lubricant delivery frequency at which lubrication is to be delivered to the plurality of lubricated regions of the vehicle. The controller device is further configured to provide control commands to cause the pump to deliver the lubricant to the plurality of lubricated regions according to the determined lubricant delivery frequency.

摘要： Apparatus and associated methods relate to quasi-adiabatic logic gates in which at least one supply terminal receives a periodic power signal. The quasi-adiabatic logic gate is configured to perform a specific logic function operative upon one or more input signals. When the quasi-adiabatic logic gate switches the output from one logic state to another logic state, the transient switching portion of the output signal substantially tracks the periodic supply signal. Such a periodic supply signal can be one that transitions gradually between low and high voltage levels. Such periodic supply signals results in a transient switching portion of the logic signal having lower frequency components than have traditional CMOS logic gate transients. The quasi-adiabatic logic gate has a periodic clock signal that is not in phase with the periodic power signal.

摘要： A backup power supply device having a short charging time is provided. The backup power supply device for supplying power when a main power supply is under a power failure includes first and second battery packs connected in parallel, a charging circuit for charging the first and second battery packs, first and second discharging switches for causing the first and second battery packs to discharge to the load device respectively, and a control unit. The control unit compares the battery voltages of the first and second battery packs with an output voltage from the main power supply. The control unit sets the first and second discharging switches to ON when the battery voltages are lower than the output voltage. When the battery voltage of the battery pack exceeds the output voltage of the main power supply due to charging, the control unit sets the first discharging switch and the second discharging switch to OFF. Thereafter, after the first and second battery packs are fully charged, the control unit switches the first and second discharging switches to ON when the battery voltage has dropped to a dischargeable upper limit voltage.
