  • Patent number: 10288664
    Abstract: The invention relates to a method and to an electrical protection device for detecting a disconnection of a protective conductor connection with a subsystem in ungrounded and grounded power supply systems and in a grounded power supply system comprising a converter system. The invention is based on the idea that the disconnection of the protective conductor connection with a subsystem will reduce the sum of the network leakage capacitances of the power supply system by the value of the network leakage capacitance of the subsystem. The necessary distinction between a subsystem in operation having a disconnected protective conductor connection and a shut-off subsystem is made by evaluating the current total power consumed via the power supply system. In the case of a converter system connected to the subsystem, the protective conductor disconnection is detected by examining the leakage current spectra that are characteristic of the converter system.

    Abstract: For electrically connecting an integrated circuit under test to a test circuit board, a test signals conduction device includes a contact member and a spring member. The contact member has a main portion, a contact portion and an extension portion. When the contact portion is pressed by the integrated circuit, the contact portion and the extension portion rotate about the main portion in a first direction, thereby causing the spring member to deform and switch to an energy storing state from a normal state. When the integrated circuit board is moved away from the contact portion, the spring member returns from the energy storing state to the normal state and causes the extension portion and the contact portion to rotate in a second direction.

  • Patent number: 10270272
    Abstract: The charge drawn from a battery during each switching event (pulse) of a pulse frequency modulated DC-DC converter is determined during a calibration period. based on differences in pulse rate with different current loading. Another approach calibration approach determines charge drawn from the battery by measuring voltage across a sense resistor while measuring the total pulse rate and while adding sufficient load current to ensure that the voltage is much larger than the residual offset of the measurement system. During operation, the system counts number of pulses are counted and the total charge drawn from the battery is determined based, at least in part, on the charge transferred per pulse during calibration, the operational mode, the battery voltage during calibration and operationally and the output voltage. Based on the total charge drawn and temperature (for temperature dependent battery types), the battery state of charge is estimated.

  • Patent number: 10255468
    Abstract: An RFID test system is disclosed that establishes a minimum coupling between two ports without an RFID tag present and a higher coupling when the RFID tag is present. Furthermore, this controlled coupling in the presence of an RFID tag is used to read and identify tags. The RFID tag is read when it is in the coupling zone, as it receives maximum power and has the lowest loss path to the receiver. Adjacent tags do not couple efficiently, so they are isolated from the wanted device (i.e., RFID tag). Further, the coupling through the RFID tag can be frequency specific, and the peak frequency can be determined. This peak frequency and also the amount of coupling can give a good indication of a number of aspects of the tag assembly.
