  • Patent number: 8935586
    Abstract: Each register in each built-in self-test (BIST) controller contains a BIST controller-specific start count value that is different from at least one other BIST controller-specific start count. A test controller provides a start command simultaneously to all the BIST controllers. This causes each of the BIST controllers to simultaneously begin a countdown of the BIST controller-specific start count values, using a counter. Each of the BIST controllers starts a test procedure in a corresponding BIST domain when the countdown completes (in the corresponding BIST controller). Thus, the test procedure starts at different times in at least two of the BIST domains based on the difference of the BIST controller-specific start count values in the different registers. Further, during the test procedure, each stagger controller can stagger the start of each BIST engine within the corresponding BIST domain to which the stagger controller is connected.

    Abstract: Apparatuses and methods are provided that minimize the effects of dark-current pulses. For example, in one embodiment of the invention, a method is provided where a first pixel is struck (i.e., a primary pixel). Pixels struck within a fixed time frame after the primary pixel is struck are referred to as secondary pixels. After a short fixed time frame has expired, the number of primary and secondary pixels is added. If the count exceeds a threshold, the primary pixel was activated by the first (or early) photon from a true gamma event. If the threshold is not met then it is likely the primary pixel generated a dark pulse that should be ignored.

    Abstract: Embodiments of the present invention include complementary metal-oxide-semiconductor (CMOS) readout architectures for photon-counting arrays with a photon-counting detector, a digital counter, and an overflow bit in each of the sensing elements in the array. Typically, the photon-counting detector is a Geiger-mode avalanche photodiode (APD) that emits brief pulses every time it detects a photon. The pulse increments the digital counters, which, in turn, sets the overflow bit once it reaches a given count. A rolling readout system operably coupled to each sensing element polls the overflow bit, and, if the overflow bit is high, initiates a data transfer from the overflow bit to a frame store. Compared to other photo-counting imagers, photon-counting imagers with counters and overflow bits operate with decreased transfer bandwidth, high dynamic range, and fine spatial resolution.

  • Patent number: 7866566
    Abstract: In a method for transferring data from a tachograph (1) onto a smartcard (3), the smartcard (3) is moved out of and back into the tachograph (1) by an electromotive drive (8) as a function of stipulated conditions. In the process, spring contacts (6) of the tachograph (1) rub over contact areas (5) of the smartcard (3) and remove any dirt which may be present. The conditions for starting the electromotive drive (8) and the intended operation of the electromotive drive (8) are stored in a memory (10) of an electronic control device (9).

  • Patent number: 7797115
    Abstract: Capacitive detection systems, modules, and methods. In one embodiment, time interval measurement(s) are generated that are monotonic functions of the capacitance(s) of capacitive sensor(s) in a capacitive sensing area. In one embodiment, the generated time interval measurement(s), or any other monotonic function(s) of capacitance(s) of capacitive sensor(s) in a capacitive sensing area, may be analyzed to detect the presence of an object near the capacitive sensing area and/or to detect the position of an object near the capacitive sensing area.

  • Patent number: 7714571
    Abstract: A method estimates variations of position of the rotor of a motor having a plurality of uniformly spaced sensors that generate a position pulse at every rotation by a pre-established angle of the rotor. The method may include generating a first clock signal at a first frequency, generating a second clock signal at a second frequency multiple than the first frequency by a first factor, in each interval between two consecutive position pulses, counting the number of pulses of the first clock signal comprised in the interval, counting the number of pulses of the second clock signal comprised in the interval. The method may also include that each time the number of counted pulses of the second clock reaches the number of pulses of the first clock counted in an interval that precedes the currently considered interval, signaling that the position of the rotor has varied of an angle equal to the ratio between the pre-established angle and the factor.

  • Publication number: 20100102203
    Abstract: A pulse data recorder system and method are provided. Upon the arrival or occurrence of an event or signal, the state of a digital switch is set. Upon receiving a pulse from a readout clock, the state of the switch is stored in a buffer memory, and the state of the switch is reset. As the readout clock is run, a time history of the state of the switch is obtained. The pulse data recorder can feature a plurality of unit cells, for use in imaging or other multiple pixel applications.

  • Patent number: 7653170
    Abstract: An electrical circuit used for measuring times is disclosed. In one embodiment, the electrical circuit has a counter, a decoder and a multiplicity of time trap elements. At least the counter and the time trap elements are located together on an integrated semiconductor component. Each time trap element has a data input, a clock input, a delay output and a output port. The time trap element contains a delay element and a flip flop. The delay element outputs a signal change at the data input with a time delay at the delay output. The flip flop has a data input, a clock input and an output port, the data inputs, the clock inputs and the output ports of the flip flop and of the time trap element being connected to one another. The time trap elements are connected as ring oscillator.

  • Publication number: 20090262883
    Abstract: A pressure-induced counter includes a pressure acquisition unit, a delay unit and a counter unit. The pressure acquisition unit is electrically coupled to the counter unit via the delay unit. The pressure acquisition unit is configured for acquiring a pressure signal of an external pressure applied thereon to generate and output an original electrical signal corresponding to the pressure signal. The delay unit is configured for processing the original electrical signal outputted from the pressure acquisition unit to obtain a processed electrical signal by depressing the leading-edge jitter existing therein. The counter unit is configured for receiving the processed electrical signal transmitted from the delay unit and taking count of the received signals.

    Abstract: In a radiation detector (10) for a time of flight positron emission tomography (PET) scanner (2), a radiation sensitive member (20) generates a signal (22) indicative of a radiation detection event. A time to digital converter (34) includes digital delay elements (40) operatively interconnected as a ring oscillator (36, 36?) and readout circuitry (50, 52, 60, 82, 84, 86, 88) configured to generate a timestamp for the radiation detection event based at least on a state of the ring oscillator when the signal is generated. Delay trim elements (46) operatively connected to the digital delay elements set a substantially common delay for the digital delay elements.
