摘要： An improved communication system for the prevention of lockup in a computer system of the binary n-cube type. Input circuitry at each of the nodes is connected for receiving messages and includes an input buffer for initially receiving the messages. Output circuitry at each of the nodes is connected for transmitting holding the messages prior to and during transmission thereof. A kernel program at each of the nodes acts as an interface between the user process programs and exclusively controls the receiving and transmitting of messages into and out of the node. There is provision for the user process programs to pass control to the kernel program to request the sending and receiving of messages by the kernel program. A lock bit is associated with each message, sensible by the user process programs, and reset by the kernel program when the kernel program has transferred the associated message. Asynchronous transfer circuitry independently and asynchronously transfers the messages as packets between the buffers of the nodes. There is logic for various decisional matters regarding message sending and receipt. There is blockout prevention logic for refusing to receive a message unless a user process program in the node has reserved a buffer of sufficient size to receive the message and for listing messages waiting to be received for which space has not yet been reserved.

摘要： A comb light source and spectrometer is disclosed. The comb light source and spectrometer can include a plurality of light emitters, where each light emitter can be configured to emit light included in a plurality of wavelength bands. Each wavelength band can be separated from an adjacent wavelength band by a noise band. Due to the separated wavelength bands for a light emitter, any signal received outside of the one or more wavelength bands can originate from noise (e.g., drift, ambient light, electrical noise), thereby enhancing signal analysis and noise rejection. In some examples, the comb light emitters can be activated sequentially such that a plurality of wavelengths across a spectrum can be measured. In some examples, the resolution and the number of spectral lines in the comb light source can be tuned by changing the properties of the quantum dots and/or increasing the number of comb light emitters.

摘要： Methods and apparatuses to perform calibration of imprecise sensors for power monitoring in a data-processing system are described. The system includes a load coupled to one or more sensors. An electronic load changes a first input signal through one or more sensors by a predetermined amount. A difference in an output signal from the one or more sensors in response to the changing is obtained. The output signal is measured and sampled. A distribution of samples of the output signal is determined. The estimated parameters of the distribution that most likely to explain actual data are determined. Next, a transfer function of the one or more sensors is determined based on the estimated parameters. The input signal through the load is accurately predicted using the transfer function of the one or more sensors to monitor the power usage by the load.

摘要： Methods and apparatus for dynamic thermal management and control within, e.g., small form-factor wireless devices such as laptop computers or cellular “smartphones”. In one embodiment, a thermal management system monitors the temperature (or other relevant criteria) for one or more components, and implements different operating states within the wireless transceiver (e.g., Wi-Fi™ or WiMAX transceiver) so as to both reduce thermal output and minimize disruption to the wireless link and/or user experience. In another embodiment, a wireless client may communicate with other clients, and/or access points, so as to cooperatively provide more options for thermal management. In addition, methods and apparatus employing “high performance” (e.g., high power output or high data rate) radios within aggressively small industrial designs are also disclosed.
