Abstract: A Phase-Locked Loop with multiphase clocks is provided. The Phase-Locked Loop includes a main loop, a calibration loop, and a Demultiplexer. The main loop includes, coupled in series, a Phase Frequency Detector, a Main Charge Pump, a Main Loop Filter, a Multi-Phase Voltage Controlled Oscillator and a Phase-switching Fractional Divider. The calibration loop includes Y Calibration Loop Filters, with Y being an integer, coupled to the Multi-Phase Voltage Controlled Oscillator, and Control Logic for controlling the Phase-Switching Fractional Divider. The Demultiplexer is coupled between an output of the Main Charge Pump and inputs of the Main Loop Filter and the Y Calibration Loop Filters. A Reference Frequency Signal is coupled to the Phase Frequency Detector, a control signal from the Control Logic is coupled to the Demultiplexer, and a Calibration Signal is coupled to a control input of the Control Logic.

Abstract: The invention relates to a manometer with a housing, a connecting piece rigidly connected to the housing, a bourdon tube arranged in the housing, a viewing glass fixed on the housing, and a pointer, which can rotate on the inside of the viewing glass and which is engaged with a free end of the bourdon tube, wherein the housing has on its top side a connecting piece that is bent inwardly for connecting to the viewing glass. To simplify the assembly, several cutouts distributed over the periphery are arranged in the connecting piece of the housing for engagement of an assembly tool, wherein the housing is connected to the connecting piece with a positive fit.

Abstract: A method, a system and computer readable medium at an electronic digital content store, such as a web site, for associating advertisement with digital content. The geographic location of the end user device receiving the encrypted digital content is determined using an address verification system. Advertisement is selected to be associated with the delivery of encrypted digital content if the address verification system returns an address in a predetermined geographic region. The address verification system includes the IP address of the end user device, the country codes found in the trace routes to the IP address, and the billing address.

Abstract: A compact and portable measuring device that is quickly and easily attachable to a fish holding device, at an end of the fish, and provides a visually readable scale, which can be used to easily identify the length of the fish and can later be read in a photograph of the fish and measuring device, even if taken at a distance away from the fish and the device.
