Abstract: An apparatus includes a local minimum identifier (408) that identifies a local minimum between overlapping pulses in a signal, wherein the pulses have amplitudes that are indicative of the energy of successively detected photons from a multi-energetic radiation beam by a radiation sensitive detector, and a pulse pile-up error corrector (232) that corrects, based on the local minimum, for a pulse pile-up energy-discrimination error when energy-discriminating the pulses using at least two thresholds corresponding to different energy levels. This technique may reduce spectral error when counting photons at a high count rate.

Abstract: A particle-counting apparatus is described, which reduces a resulting width of pulses when a charge pulse is received from a particle detector, thereby reducing pile-up problems with pulses. Pulse shortening is obtained by resetting the pulse shortly after it exceeds its peak level at the apparatus output. The apparatus includes a charge-sensitive amplifier and a shaper which generates an output for subsequent discrimination circuits. A reset generator monitors the shaper output and generates a reset signal to the shaper when a peak has been detected.

Abstract: A system and method for digital communication wherein a host provides a host clock and a clockless device transmits to the host a bit stream synchronized according to the clock at a data rate that is an integer multiple of the clock rate. A training mechanism using training data detects time skew between host clock and bit stream, and a digital skew compensation mechanism compensates, substantially in real time, for the skew and for variations in the skew that may occur with the passage of time, in accordance with a vote among at least three samples of a bit of the bit stream, subsequent sampling being retarded or advanced if, respectively, an early or late sample is in disagreement with the vote. Preferably, the compensation value is selected from at least four possible compensation values, and can be stored in a memory to hasten subsequent restarts of the system.

Abstract: Apparatus includes an external device (600) including a mount, e.g., eyeglasses (25), which is placed in front of a subject's eye (4). A power source (24) is coupled to the mount and emits energy toward the eye (4). An intraocular device (60) is implanted entirely in the subject's eye (4), and includes a control unit (200), stimulating electrodes (1064), and an energy receiver (32), which receives the energy from the power source (24) and generates a voltage drop. Photosensors (34) detect photons (33) and generate a signal. Driving circuitry (36) is coupled to the energy receiver and the photosensors, and drives the electrodes to apply electrical charges to a retina (6) in response to the signals from the photosensors (34). The external device modulates the emitted energy, and the control unit demodulates the modulated energy to regulate an operation parameter of the intraocular device. Other embodiments are also described.
