Abstract: Samples of a light radar (“LIDAR”) return signal are stored in an analog circular buffer following the transmission of a LIDAR pulse. Sampling continues for a fixed period of time or number of samples during a post-trigger sampling period after the occurrence of a trigger signal from a trigger circuit. The trigger circuit indicates the receipt of a return pulse associated with a target object based upon one or more return signal characteristics. Following the post-trigger sampling period, the stored analog samples are sequentially read out and converted to digital sample values. The digital sample values may be analyzed in a digital processor to further confirm the validity of the returned LIDAR pulse, to determine a time of arrival of the LIDAR pulse, and to calculate a distance to the target object. Some versions include multiple circular buffers and capture clocks, enabling the capture of samples from multiple return pulses.

Abstract: An apparatus having an X-ray sensor assembly with X-ray blocking pixels divided by X-ray transmitting gaps with the X-ray blocking pixels casting an X-ray blocking shadow; and a die containing signal processing electronics, with the signal processing electronics positioned substantially entirely within the X-ray blocking shadow. A method for detecting the alignment between the X-ray sensor assembly and the die is disclosed. Also disclosed is an X-ray computed tomography machine having a printed circuit board (“PCB”), a die embedded in the PCB, and a signal source wherein signals are routed to and from the die by traces on at least one of the surfaces of the PCB.

Abstract: A method of authenticating includes providing a glucose test strip having a top surface with a reagent thereon that has a structure which chemically reacts with glucose and an anti-counterfeiting identification feature (identification feature) including at least one ink. The glucose test strip is inserted into a glucose meter. The glucose meter includes a light source positioned to shine light on the ink after the inserting, a photodetector positioned to detect a reflected or transmitted signal after interaction with the ink, and stored information that identifies the identification feature. A processor implementing an algorithm automatically analyzes the reflected or transmitted signal by reference to the stored information to determine whether the glucose test strip is authentic.

Abstract: A system and method for reducing power consumption in an inactive device. Based upon inputs received from one or more sensors, a processor in a device determines that the device has not moved or has been inactive for a predetermined period. One or more components of the device are placed in an inactive state or in a sleep mode when the device has been inactive for the predetermined period. The inactive state or sleep mode requires less power consumption by the components than an active mode of operation. A piezoelectric sensor in the device is used to detect movement. The piezoelectric sensor provides an input signal to the processor upon detecting movement of the device. The one or more components are placed in the active mode in response to the input signal.

Abstract: An integrated circuit provides digital output signals in either single-ended or differential form on a shared set of pins. A control circuit generates signals to ensure that when one form (single-ended or differential) of outputs are being provided, outputs in the other form are disabled. Outputs in differential form may be provided at twice the frequency as compared to the outputs in single-ended form. As a result the same number of pins can be supported for both single-ended and differential outputs for a desired data throughput, and the pin count of the integrated circuit is reduced.

Abstract: An electronic device evaluation system (100) includes a potential customer located at a site (102) that accesses a company site (106) via a computer network such as the internet (104). The company site (106) includes a computer such as a server (108) which is coupled to one or more evaluation boards (110, 112) and instrumentation (114). Using the system (100) a potential customer or visitor can remotely evaluate an electronic device or system of interest using parameters he selects and the results are sent back after the evaluation is conducted at the company site (106). Using system (100) potential customers, site visitors, etc. can evaluate electronic devices/systems of interest in real-time without the need to purchase an evaluation board and spend the time and resources needed to conduct the tests.
