  • Patent number: 11960202
    Abstract: An EUV microscope device utilizing a source of a beam of EUV light. The light is sent to a collector which produces a first focused EUV beam. A monochromator receives the first focused EUV beam and produces a second EUV beam that is passed to an illumination module. The output of the illumination module is passed to a mask. The reflected beam from the mask is sent to a zone plate and a detector to produce an image.

  • Publication number: 20190245963
    Abstract: The present invention relates to a SIM multiplexing device that provides a mechanism for multiplexing multiple SIM cards into a single SIM device. The SIM Mux device interfaces to the host device via the host device's standard SIM slot. The SIM Mux application resides on the SIM Mux logic device and communicates with the device over the SIM slot's SIM I/O line using standard ISO-7816 messages. The SIM Mux application allows a user to select the active SIM slot via a SIM application interface and directs the logic device which SIM socket to activate on the shared SIM I/O line, thus enabling the user to utilize any one of the populated SIM cards at one time.

  • Patent number: 7138781
    Abstract: A system and method for controlling a fan is disclosed. In one embodiment, a fan controller is integrated in silicon and uses an embedded microcontroller to implement a digital fan control algorithm. The microcontroller may continually monitor temperature and sample the speed of the controlled fan. The speed of the fan may be compared to RPM values fitted on a desired curve that is representative of the Temperature-versus-RPM function for the given controlled fan. The fan control algorithm may be based on a PID compensator or a Ramp Rate Closed-loop controller (RRCC), which may be operated to drive the fan to the desired speed. The fan may also provide a Fan ID feedback signal to the microcontroller, which may use the Fan ID feedback signal upon system start-up to initialize the PID compensator gain settings or the RRCC parameter settings, and select the appropriate Temperature-versus-RPM function curve based on pre-determined values for the given fan.

  • Patent number: 5450715
    Abstract: A wheel assembly for attachment to hand-held devices such as trimmers, edgers, blowers, metal detectors and the like includes a wheeled frame having a clamp arranged to be freely secured to the wand of a device for rotation of the wand therein. Stop members engage the wand on each side of the clamp to prevent relative longitudinal sliding movement of the wand and the clamp. The wheel assembly is thus able to be mounted on and retained in a desired position on the wand while still permitting the wand to be rotated as desired to orient the working end of the device, as for example with a string trimmer device, between a mowing orientation and an edging orientation.
