Abstract: The present disclosure advantageously provides a system method for efficiently multiplying matrices with elements that have a value of 0. A bitmap is generated for each matrix. Each bitmap includes a bit position for each matrix element. The value of each bit is set to 0 when the value of the corresponding matrix element is 0, and to 1 when the value of the corresponding matrix element is not 0. Each matrix is compressed into a compressed matrix, which will have fewer elements with a value of 0 than the original matrix. Each bitmap is then adjusted based on the corresponding compressed matrix. The compressed matrices are then multiplied to generate an output matrix. For each element i,j in the output matrix, a dot product of the ith row of the first compressed matrix and the jth column of the second compressed matrix is calculated based on the bitmaps.

Abstract: A plug-in point adapter provides a self-contained adapter assembly that may be plugged into the connector jack of an existing electrical alligator clip probe and which increases the length of the probe. In some implementations, the adapter includes a test point that can be projected forward to a selectable length between the jaws of the clip that allows the clip to be used either as the point of a test probe or the original service as an alligator probe. In some implementations, the adapter transfers the alligator jack to the adapter jack for connection of the test lead plug. In some implementations, the adapter latches to the alligator clip and remains on permanently. The original alligator clip is not modified in any way and therefore the adapter can be customized for various designs of alligator clips that do not have to be modified.

Abstract: A processor of a computing device is described that receives user input to disable an application and determines whether the application is passive-enabled. Responsive to determining that the application is passive-enabled, the computing device causes the application to operate in a passive state. While the application operates in the passive state, one or more essential functions or services provided by the application that are required by an operating system of the computing device are enabled and any remaining functions or services provided by the application are disabled. After causing the application to operate in the passive state: the computing device outputs an indication that the application has been disabled in response to the user input to disable the application, and performs one or more operations that rely on the one or more essential functions or services provided by the application.

Abstract: An apparatus and method are provided for processing a received input signal comprising a sequence of data blocks. Counter circuitry within the apparatus is arranged to receive a digital representation of the input signal, and for each data block generates a count value indicative of occurrences of a property of the digital representation (for example a rising edge or a falling edge) during an associated data block transmission period. Quantization circuitry then maps each count value to a soft decision value from amongst a predetermined set of soft decision values, where the number of soft decision values in the predetermined set exceeds a number of possible data values of the data block. The output circuitry then generates a digital output signal in dependence on the soft decision values.
