Abstract:
Systems and methods of recovering a device from a sleep mode of operation are described. In one aspect, a device includes a sleep recovery circuit that is operable to transition from a first signal detection mode to a second signal detection mode in response to detection of a first signal characteristic in an input signal. The sleep recovery circuit also is operable to transition from the second signal detection mode to a third operational mode in response to detection in the input signal of a second signal characteristic different from the first signal characteristic.
Abstract:
A compressor has a housing defining a gas inlet flow path and a gas outlet and a rotatable impeller wheel between the gas inlet flow path and the gas outlet. The housing has an inner wall defining a surface located in close proximity to radially outer edges of impeller wheel vanes that sweep across said surface as the impeller wheel rotates. At least one opening is provided in the inner wall at the surface. A port is provided in the compressor housing in gas communication with the at least one opening and for diverting gas in a direction away from the gas inlet flow path during relatively low gas flow rate conditions. A gas displacement device such as a pump is disposed outside of the gas inlet flow path and connected to said port, the pump being operable to remove gas selectively through the at least opening and the port in a direction away from said gas inlet flow path.
Abstract:
The method is for attaching an attachment plate to an elongate member. An attachment plate (10) is provided that has a spiral shaped cutout forming a fastener (22). The fastener (22) is pulled out and away from a bottom surface (14) against a biasing force of the fastener (22). An elongate member (30) is inserted into the fastener (22) so that the elongate member (30) is captured between the fastener (22) and the bottom surface (14). An outer end (24) at least partially wrapped around the elongate member (30). An inner edge (32) of the fastener (22) bears against the elongate member (30).
Abstract:
This invention relates to processes useful for fabricating electronic devices, more particularly to a process for laminating a layer of dielectric material onto a semiconductor.
Abstract:
A detachable fixing is formed from a single length of elongate material bent into first and second loop regions. One or both of the loop regions is formed as an elongate loop having a point of entry which is resiliently biased closed by the nature and formation of the material, and has one end of the elongate material disposed to form an exit from the loop.
Abstract:
The attachment plate (2) is made of a flexible, bendable material. The attachment plate has two tongue shaped portions including a first tongue and a second tongue formed by a perforation in the plate so that a foot portion of each tongue shaped portion is held to the plate while each respective tongue shaped portion, extending from the foot portion to an outer free end of each tongue shaped portion, respectively, is outwardly bendable from the plate and the outer free ends of the tongue shaped portions are immediately adjacent to one another at a slit formed by a perforation.
