  • Patent number: 9396913
    Abstract: A charge read-out structure for photon and particle detectors, which is capable of spatially-resolving a position of the charge. The structure comprises a resistive element defining a detection surface which is capacitively coupled to an array of electrically insulated electrodes. Each electrode in the array is capacitively coupled to an adjacent electrode in the array to form a capacitively coupled network of electrodes. Selected ones of the electrodes in the array are each coupled to an array output for connection to a respective charge measurement device. The resistive element has a resistivity sufficient to temporarily localize a charge induced on the resistive element to an area corresponding to a subset of said electrodes in the array and for a duration sufficient for signal measurement from the array of electrodes.

  • Patent number: 9337676
    Abstract: An enclosure includes a housing adapted to cover at least the body of a power adaptor of a device charger. The housing has an opening to allow access to the charging wire port of the power adaptor. The opening is smaller than the power adaptor, so the power adaptor cannot be removed from the housing through the window. Further, the window can permit the charging wire plug to be plugged into and removed from the charging wire port while the power adaptor remains in the housing. The housing further includes charging wire trap which captures the charging wire. The charging wire trap holds the wire between the charging wire plug and the device interface. The charging wire trap is sized to not allow either the charging wire plug or the device interface to pass through it. The enclosure can also include an anchor point attached to the housing.

  • Patent number: 9285406
    Abstract: In an impedance measurement system, a reference impedance (2) to be measured is periodically connected and disconnected by means of switch (3) in parallel to the unknown impedance (1) to be measured. The thus generated amplitude modulation of the measurement current is demodulated, and the amplitude of the demodulated signal is indicative of the reference impedance to be measured. Using a low frequency modulation of the reference impedance enables to measure the impedance of the reference impedance without disconnecting the unknown impedance.

  • Patent number: 9257352
    Abstract: A test wafer is disclosed with a first side configured to have integrated circuits formed thereon and a second side with a test structure formed thereon. The test wafer can include electrical test structures embedded in the second side of the wafer. An electrical test of the test wafer can be performed after handling by a tool used in a wafer manufacturing process to determine if the tool caused a defect on the second side of the wafer. The test structure can include a blanket layer disposed on the second side of the wafer. The test wafer can then be exposed to a wet etch and inspected thereafter for the presence of an ingress path caused from the etch chemistry. The presence of an ingress path is an indication that the tool used prior to the wet etch caused a defect in the wafer.
