  • Patent number: 10505379
    Abstract: A battery jump starting connection detection system and method assists in making the best connection to the vehicle battery by detecting the connection resistance to the battery. The connection resistance measurement is taken with the jump start battery isolated from the battery and involves placing a load of known resistance on the battery via the clamps and cabling, and measuring the voltage differential in loaded and unloaded states. The connection resistance is calculated in a main controller, given the loaded and unloaded voltages. As the user adjusts the jump start clamps on the battery terminals in order to get the best possible contact, the system measures the resistance and the results are presented on a display in a meaningful, easy-to-read format such as an LCD display. The user can thus optimize the connection while seeing the results of the optimization in real time.

  • 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.

The controller includes a processor, a memory device, a first input pin coupled to the first signal source to receive the AC signal, a second input pin coupled to the second signal source to receive the second signal, and an analog to digital (A/D) converter. The A/D converter is coupled to the first input pin and the memory device storing instructions that when executed by the processor cause the processor to sample the second signal at the second input pin only when the first signal has a value of about zero volts at the first input pin.

  • Patent number: 10078101
    Abstract: A testing device for wafer level testing of IC circuits is disclosed. An upper and lower pin (22, 62) are configured to slide relatively to each other and are held in electrically biased contact by an elastomer (80). To prevent rotation of the pins in the pin guide, a walled recess in the bottom of the pin guide engages flanges on the pins. In another embodiment, the pin guide maintains rotational alignment by being fitted around the pin profile or having projections abutting the pin. The pin guide (12) is maintained in alignment with the retainer 14 by establishing a registration corner (506) and driving the guide into the corner by elastomers in at least one diagonally opposite corner.

  • Patent number: 10012686
    Abstract: A probe includes a self-aligning connector set, a moveable probe tip, a cable, a housing, and a spring. When the probe tip is pressed to a test point on a device-under-test, the probe tip moves within the housing to cause a first connector and a second connector of the self-aligning connector set to be connected through an adapter of the self-aligning connector set, thereby establishing a signal path through the probe. The first connector, second connector, and adapter are structured so that their respective ground conductors become connected prior to their respective signal conductors becoming connected. Electro-static charge present at the test point is safely discharged through a resistor to ground before the signal path through the probe is established, thereby preventing damage to the probe and connected host instrument. When the probe tip is removed from the device-under-test, the spring forces a disconnection of the first and second connectors.
