  • Patent number: 9027759
    Abstract: A sorting apparatus is described, and which includes a conveyor which transports a produce stream for inspection. A product separation surface is mounted near the distal end of the conveyor, and the produce stream passes over the product separation surface, and is slowed to a speed such that the produce stream falls substantially immediately vertically downwardly. An inspection zone is located downstream relative to the product separation surface. An imaging device is provided, and which images the produce stream passing through the inspection zone; an illumination device is provided for illuminating the produce stream passing through the inspection zone, and an ejector assembly is located downstream of the inspection zone and which removes unwanted solid material in the produce stream having undesirable characteristics.

  • Publication number: 20150090052
    Abstract: A pressure sensor (20) includes a test cell (32) and sense cell (34). The sense cell (34) includes an electrode (42) formed on a substrate (30) and a sense diaphragm (68) spaced apart from the electrode (42) to produce a sense cavity (64). The test cell (32) includes an electrode (40) formed on the substrate (30) and a test diaphragm (70) spaced apart from the electrode (40) to produce a test cavity (66). Both of the cells (32, 34) are sensitive to pressure (36). However, a critical dimension (76) of the sense diaphragm (68) is less than a critical dimension (80) of the test diaphragm (70) so that the test cell (32) has greater sensitivity (142) to pressure (36) than the sense cell (34). Parameters (100) measured at the test cell (32) are utilized to estimate a sensitivity (138) of the sense cell (34).

  • Patent number: 8963538
    Abstract: Manufacturing of magnetometer units (20?) employs a test socket (41) having a substantially rigid body (43) with a cavity (42) therein holding an untested unit (20) in a predetermined position (48) proximate electrical connection (50) thereto, wherein one or more magnetic field sources (281, 332, 333, 334, 335, 336) fixed in the body (43) provide known magnetic fields at the position (48) so that the response of each unit (20) is measured and compared to stored expected values. Based thereon, each unit (20) can be calibrated or trimmed by feeding corrective electrical signals back to the unit (20) through the test socket (41) until the actual and expected responses match or the unit (200) is discarded as uncorrectable. In a preferred embodiment, the magnetic field sources (281, 332, 333, 334, 335, 336) are substantially orthogonal coil pairs (332, 333, 334) arranged so that their centerlines (332-1, 333-1, 334-1) coincide at a common point (46) within the predetermined position (48).

  • Publication number: 20150048848
    Abstract: A test structure includes two capacitor structures, wherein one of the capacitor structures has conductor plates spaced apart by a cavity, and the other capacitor structure does not include a cavity. Methodology entails forming the test structure and a pressure sensor on the same substrate using the same fabrication process techniques. Methodology for estimating the sensitivity of the pressure sensor includes detecting capacitances for each of the two capacitor structures and determining a ratio of the capacitances. A critical dimension of the cavity in one of the capacitor structures is estimated using the ratio, and the sensitivity of the pressure sensor is estimated using the critical dimension.

  • Publication number: 20140352400
    Abstract: Embodiments of packaged transducer-including devices and methods for their calibration are disclosed. Each device includes one or more transducers, an interface configured to facilitate communications with an external calibration controller, a memory, and a processing component. The external calibration controller sends calibration commands to the transducer-including devices through a communication structure. The processing component of each device executes code in response to receiving the calibration commands. Execution of the code includes generating transducer data from the one or more transducers, calculating calibration coefficients using the transducer data, and storing the calibration coefficients within the memory of the device.

  • Publication number: 20140345380
    Abstract: A mechanism for recovering from stiction-related events in a MEMS device through application of a force orthogonal to the stiction force is provided. A small force applied orthogonal to the vector of a stiction force can release the stuck proof mass easier than a force parallel to the vector of the stiction force. Example embodiments provide a vertical parallel plate or comb-fingered lateral actuator to apply the orthogonal force. Alternate embodiments provide a proof mass of a second transducer to impact a stuck MEMS actuator to release stiction.

  • Publication number: 20140303926
    Abstract: Embodiments of systems for calibrating transducer-including devices include a board support structure, one or more motors, a motor control module, and a calibration control module. The board support structure holds a calibration board in a fixed position with respect to the board support structure. The motor(s) rotate the board support structure around one or more axes of a fixed coordinate system. The motor control module sends motor control signals to the motor(s) to cause the motor(s) to move the board support structure through a series of orientations with respect to the fixed coordinate system. The calibration control module sends, through a communication structure, signals to the transducer-including devices, which are loaded into a plurality of sockets of the calibration board. The signals cause the transducer-including devices to generate transducer data while the board support structure is in or moving toward each orientation of the series of orientations.

  • Patent number: 6628856
    Abstract: The optical switch includes input optical fibers, output optical fibers, a lens, a movable mirror, and an actuator operative to move the mirror. Depending on a voltage applied to the actuator, the actuator selectively set the mirror to a first position corresponding to a first combination of optical paths, through which the light beam travels from the first set of the input optical fibers to the second set of the output optical fibers; and to a second position corresponding to a second combination of optical paths, through which the light beam travels from the first set to the second set. The first combination is different from the second combination, and a number of optical fibers of the first set and the second set is more than two.
