Abstract: An example gesture detection method includes detecting at a first time a first touch on a touch panel, where the first touch covers a first area of the touch panel, and then determining whether the first touch is within a track region that surrounds a fingerprint sensing region. The method includes determining whether the first touch is within the fingerprint sensing region, the fingerprint sensing region including a sensing surface of a fingerprint sensor. The method includes determining a first fraction of the fingerprint sensing region covered by the first touch and determining whether the first fraction exceeds a first threshold. The first threshold is a majority of the fingerprint sensing region. The method includes determining a second fraction of all of the first area that is within the fingerprint sensing region and determining whether the second fraction exceeds a second threshold, where the second threshold is a fraction indicative of a majority of an area associated with the corresponding touch. The method includes based on determining that the second fraction exceeds the second threshold, determining whether the first touch is valid.

Abstract: A method includes receiving, at a master agent, announcements from candidate consumer agents indicating the presence of the candidate consumer agents. Each announcement includes display parameters for a display of the corresponding candidate consumer agent. The method further includes receiving at the master agent content parameters from a producer agent, the content parameters defining characteristics of content to be provided by the consumer agent. A mosaic screen is configured based on the received announcements and the content parameters. This configuring of the mosaic screen includes selecting ones of the consumer agents for which an announcement was received and generating content distribution parameters based on the content parameters and the display parameters of the selected ones of the consumer agents. The generated content distribution parameters are provided to the consumer agent.

Abstract: An in-memory computation (IMC) system includes an in-memory computation circuit formed by a first phase change memory (PCM) array configured to store the computational weights for an in-memory computation operation. A data storage circuit is formed by a second PCM array configured to store backup data for the computational weights for the in-memory computation operation. The first PCM array includes PCM cells made of a phase change material provided by a first GST alloy, and the second PCM array includes PCM cells made of a phase change material provided by a second GST alloy different from the first GST alloy. A control circuit operates to read the backup data from the second PCM array and write to the first PCM array to refresh the computational weights for the in-memory computation operation from the backup data.

Abstract: A DC-DC converter includes a primary-side control-circuit having an oscillator driving a transformer in response to assertion of a PWM-signal to transmit power from the primary to the secondary and ceasing in response to deassertion of the PWM-signal, and a receiver demodulator circuit receiving/demodulating a feedback signal sent from the secondary to the primary by comparing an instantaneous value of an envelope indicative of voltages at the primary-coil to an average-value of the envelope to produce a reset-signal. A PWM circuit asserts the PWM-signal in response to a set-signal and deasserts the PWM-signal in response to assertion of the reset-signal. A secondary-side control-circuit rectifies the received power, asserts an intermediate feedback-signal if feedback indicative of the output voltage is greater than a reference-voltage, and connects a capacitance between the secondary and ground in response to assertion of the intermediate feedback-signal to modulate and send the feedback to the primary.

Abstract: A Low Voltage Differential Signaling (LVDS) transmitter includes driver circuit with a first transistor, a second transistor, a third transistor, a fourth transistor, a first resistor, and a second resistor. The first transistor is coupled between a first node and first output. The second transistor is coupled between the first node and a second output. The third transistor is coupled between the first output and a second node. The fourth transistor is coupled between the second output and the second node. The first resistor is coupled between the first output and a common mode node. The second resistor is coupled between the second output and the common mode node. A pre-driver circuit generates gate control signals controlling the first, second, third, and fourth transistors in response to a data signal. A controlled timing delay is applied to the timing of logic state transistors for the control signals.

Abstract: A startup circuit includes a first circuit leg coupled between an input node and an output node and a second circuit leg coupled between the input node and the output node. The first circuit generates a first current and the second circuit leg sinks current from a first node based upon the first current. A third circuit leg is coupled between the input node and the output node and sources current to a second node based upon a voltage at the first node to thereby generate a feedback voltage at the second node. The first circuit leg increases the first current based upon the feedback voltage, in turn increasing the current sunk from the first node by the second circuit leg and increasing the current sourced to the second node by the third circuit leg to thereby generate a startup current at the output node.
