Appl. No.:

09/773108

Inventors:

Tatyana Feldman - Newport Beach CA
Wei Wang - Irvine CA

Assignee:

Numed/Tech LLC - Newport Beach CA

International Classification:

A61F 606

US Classification:

128831, 128843, 604 1, 60438517

Abstract:

Disclosed are occluders and methods of their use. The occluders comprise shape-memory polymeric materials which, when heated above their crystalline melting temperatures, may be deformed from a first configuration into a second configuration. The occluder is then held in the deformed shape until it cools to a temperature below its crystalline melting temperature (T ) whereby it holds the deformed shape of the second configuration by virtue of the recrystallization of the polymeric occluder material. Upon reheating the occluder above its T , the occluder will resume its original shape. In this manner, an occluder which has been deformed to reduce its diameter may be inserted into and positioned within a target lumen in the body and then allowed to warm to body temperature whereby it resumes its original diameter and results in the occlusion of the lumen. The occluders, according to preferred embodiments, may be used for reversible sterilization of mammals, among other surgical and non-surgical uses.

Semtech Corporation - Newbury Park CA

International Classification:

G06F 1300

US Classification:

710110, 713322, 713600

Abstract:

A system is described in which the Master can stop its clock and go into a low-power state (for power conservation reasons) at arbitrary times. Before going into the stopped-clock or low-power mode, the Master checks that the serial bus is idle (defined as both Clock and Data lines being âHighâ). A latch circuit is provided which is active when them aster is in low-power mode. The latch circuit watches for the very first negative-going clock pulse (from the slave), and its configuration is such that when latched, it holds the clock line low. Holding the clock line low prompts the slave to discontinue efforts to send the data. Stated differently, the slave will not conclude that it had successfully sent its data, and this prompts the slave to retain a copy of its data for later resending.

International Classification:

G06F 1312

US Classification:

710 72, 710 8

Abstract:

A wireless host is used with a computer having a BIOS, an operating system, a serial bus interface coupled with the BIOS, the wireless host operating under a protocol that functions only in the presence of a corresponding wireless communications driver in the operating system, and the BIOS characterized in that human interface device information received via the serial bus interface is made available to the operating system by means other than the wireless communications driver. Human interface device information is received via the wireless host. Depending on a predetermined condition, the human interface device information is passed to a wireless communications driver in the operating system, or is passed to the serial bus interface and is made available to the operating system by means other than the wireless communications driver. The predetermined condition may be the absence of the wireless communications driver, or for example may be the determination that the human interface device information is an escape sequence. In this way, user communications to the computer can be robust even in the event of operating system or software failure.

International Classification:

G09G 5/00

US Classification:

345173, 345174

Abstract:

A Circuit (in FIG. ) and an Algorithm for Data Acquisition from Capacitive Touch Pad Sensor employs charge transfer to sense capacitance. The circuit has high degree of noise rejection from both system and externally generated noises; it is resistant to the effects of ESD; utilizes a general purpose “off the shelf” components and programmable microcontroller (element ), providing flexibility for changes and adjustments without incurring the high costs of a custom IC design. A settling time and low sensitivity to the noise.
