Abstract: A system includes a pressure sensor and circuitry to collect information from the pressure sensor and transmit the information to a server. The pressure sensor and circuitry are formed as an integrated node adapted to be placed to sense pressure in the foot of an animal. The server processes the information to one or more devices.

Abstract: A delay locked loop generates a voltage on a common node as a function of a phase difference between a reference input and a feedback input. A first voltage-controlled delay line coupled between the reference input and the feedback input and has a first delay, which is controlled by the voltage on the common node. A second voltage-controlled delay line is selectively coupled in series with the first delay line, between the reference input and the feedback input, as a function of a test control input. The second delay line has a second delay, which is controlled by the voltage on the common node.

Abstract: A scannable dynamic logic element includes a clock input, a test enable input, a data output, a precharge circuit, a boolean pull-down circuit and a test scan pull-down circuit. The precharge circuit is coupled between a first supply terminal and the data output and has a precharge control input coupled to the clock input. The boolean pull-down circuit is coupled between the data output and the second supply terminal and has a logic data input, a first evaluation control input which is coupled to the clock input and a first enable input which is coupled to the test enable input. The test scan pull-down circuit is coupled between the data output and the second supply terminal and has a test data input, a second evaluation control input which is coupled to the clock input and a second enable input which is coupled to the test enable input.

Abstract: A tag memory circuit includes an address index input, an address offset input and an integrated adder and pre-decode circuit. The integrated adder and pre-decode circuit has a first addend input coupled to the address index input, a second addend input coupled to the address offset input, and a pre-decoded sum output. A final row decode and word line driver circuit is coupled to the pre-decoded sum output and generates a word line output which is coupled to the address inputs of a tag memory array. The data outputs of the tag memory array are coupled to a sense amplifier.
