摘要:
An architecture and method are provided for preventing snapdown in a voltage controlled MEMS device having a movable actuator with an actuator electrode coupled to a high voltage power supply (HVPS) through a drive circuit, the movable actuator suspended over a cavity electrode formed on a substrate and coupled to a common backplane supply (VssC). Generally, the circuit includes a number of first diodes coupled between the HVPS and the actuator electrode and/or the cavity electrode to provide a forward-biased path to transfer a positive charge to the HVPS when the accumulated charge exceeds a predetermined threshold. Preferably, the drive circuit further includes second diodes to provide a low impedance path to transfer a positives charge from the actuator electrode and/or the cavity electrode to a substrate ground when the accumulated charge results in or exceeds a predetermined threshold voltage. Other embodiments are also disclosed.

One example of an ESD protection circuit (100) can include a p-channel field effect transistor (PFET) (110) having a source-drain path connected between a pad (102) and a protected circuit (106). In an ESD event, PFET (110) can provide an ESD discharge path between pad (102) and a high power supply node (114) or low power supply node (112).

摘要:
A combination of a master cylinder and a fluid reservoir includes a master cylinder, a reservoir, and a pair of elastomeric seals between the master cylinder and the reservoir. The master cylinder has a first bore which defines a first reservoir seat and a second bore which defines a second reservoir seat. The first bore and the second bore are spaced a predetermined distance from each other. The master cylinder also has a rigid snap-in attachment seat disposed between the first bore and the second bore. The reservoir has a first cylindrical seating projection and a second cylindrical seating projection spaced the predetermined distance from the first seating projection. A snap-in attachment member is disposed between the first and second seating projections for alignment with and engagement with the snap-in attachment seat. The seals are disposed between each of the first bore and the first seating projection and the second bore and the second seating projection. When the snap-in attachment member is engaged with the attachment seat, the seals are both compressed between the reservoir and the master cylinder preventing any fluid leakage therepast.
摘要:
An apparatus includes a charge pump array including multiple charge pump cells. The charge pump array is configurable into a first arrangement of the charge pump cells coupled in series or a second arrangement of the charge pump cells coupled in parallel. The apparatus can include reconfiguration circuitry configured to select the first arrangement of the charge pump cells or the second arrangement of the charge pump cells. The charge pump array is configured to alter a voltage level of a signal based, at least in part, on the selected arrangement of the charge pump cells.

A case accessory for a portable electronic device that includes a cleaning system is disclosed. In some embodiments, the case accessory may include a back cover configured to secure a portable electronic device, a front cover rotationally coupled to the back cover, and a cleaning mechanism integrated into the front cover including a buffer configured to clean a surface of the portable electronic device.
摘要:
Contact centers typically have an entry process to receive incoming contacts and distribute those appropriately amongst agents associated with the contact center. This entry process is often complex and time consuming. This invention allows users of the contact centre to reach a particular agent without undergoing the entry process. This is achieved without compromising security or giving away details about the agents.
