US Patent:

60844795, Jul 4, 2000

Filed:

May 28, 1998

Appl. No.:

9/086124

Inventors:

Michael L. Duffy - Austin TX
Paul H. Scott - San Jose CA

Assignee:

Cypress Semiconductor Corp. - San Jose CA

International Classification:

H03L 700

US Classification:

331 17

Abstract:

An apparatus comprising a phase-locked loop, a select circuit and a control circuit. The phase-locked loop may be configured to generate a feedback signal (along with a buffered output signal) in response to a reference clock and a control signal. A select circuit may be configured to present a reference clock signal in response to a plurality of input clock signals and a select signal. The slew control circuit may be configured to generate the control signal in response to the select signal, and the feedback signal. The control circuit may be used to reduce noise presented to the phase-locked loop and may allow for a rapid initial frequency acquisition of the PLL to the reference frequency.

Abstract:

A wire line removable well safety valve in an oil and gas well completion design including a tubing string, a well packer around the tubing string sealing with the well casing, and a submergible well pump on the tubing string below the packer. The safety valve controls flow of pumped well fluids through the tubing string, directs separated gas into the casing annulus around the tubing string above the packer, and shuts off the flow of pumped fluids and separated gas to the surface while permitting recirculation of pumped well fluids between the annulus and tubing string below the packer. The safety valve includes a housing having separate central and annular flow passages for pumped fluids and separated gas, respectively, a ball valve for controlling flow of pumped fluids in the central flow passage, an annular bypass valve for controlling flow of separated gas along the annular flow passage, and a recirculating valve between the central and annular flow passages for recirculation of pumped fluids when the ball and bypass valves are closed. The safety valve is held open hydraulically from the surface and includes means for closing the valve when hydraulic pressure fails, shutting off the flow of pumped fluids and bypass gas while permitting continuous operation of the well pump by recirculating pumped fluids below the packer.

Inventors:

Paul William Scott - Flower Mound TX, US

International Classification:

B60R 1/06
B60R 1/08

Abstract:

A rearview mirror mountable on an electric scooter or similar devices provides visibility for users of the devices. The rearview mirror comprises a mirror with a curved surface and a mounting structure configured to mount the mirror above a steering shaft of the vehicle. The mounting structure is configured to connect to the vehicle around the steering shaft of the vehicle and the mirror is connected to the mounting structure such that the rearview mirror is located above the steering shaft.
