Appl. No.:

11/652933

Inventors:

Wayne T. Holcombe - Mountain View CA, US
Robert Gordon Farmer - Modesto CA, US

Assignee:

Silicon Laboratories Inc. - Austin TX

International Classification:

H01L 27/15
H01L 29/267
H01L 31/12
H01L 33/00

US Classification:

257433, 257 81, 438 25

Abstract:

An optoisolator device is shown having a die attachment device with a planar surface. A first circuit die has first and second planar surfaces and a first side surface. A receiver circuit and a first photodiode are formed on the first planar surface of the first circuit die, where the first photodiode is electrically coupled to the receiver circuit. The second planar surface of the first circuit die is attached to the planar surface of the die attachment device. A second circuit die has a transmitter circuit that includes a first light emitting diode and is attached to the die attachment device in a position adjacent to the first side surface of the first circuit die. A clear plastic layer is formed on the planar surface of the die attachment device over the first and second circuit dies. An opaque layer may be formed over the clear plastic layer.

International Classification:

H04B 10/00

US Classification:

398138, 398135, 398130, 398128, 398115

Abstract:

A communication device is disclosed having optical and near-field communication capability. The device includes an optical transceiver circuit fabricated on an integrated circuit die and configured to transmit and receive far field signals. A near field transceiver circuit is also fabricated on the integrated circuit die and is configured to transmit and receive near-field electro-magnetic signals. Control circuitry is provided to selectively enable the optical transceiver circuit and the near field transceiver circuit responsive to an external control signal.

Appl. No.:

6/234306

Inventors:

Robert B. Farmer - Boulder CO

Assignee:

Thompson Respiration Products, Inc. - Boulder CO

International Classification:

A61M 1600

US Classification:

12820518

Abstract:

A portable positive displacement respirator/ventilator is provided for both a pressure sigh and a volume sigh of predetermined duration and frequency by providing a variable length crank arm connecting a piston through a connecting rod by mounting the connecting rod on a circular toothed gear, pivoting the gear for movement at its center and driven on its outer edge with a separate motor driven pivot gear which when moved relocates the effective length of movement of the point of attachment of the connecting rod thereby changing the volume swept by the piston for the same arc of reciprocal movement of the larger circular toothed gear enabling both a volume change or a volume sigh with the device. A cooperating multiplicity of adjustable pressure regulating valves where at least one can be intermittently closed during the operation of the device regulates ventilation pressure or breathing pressure and sigh pressure.

Assignee:

Lifecare International, Inc. - Lafayette CO

International Classification:

F16K 11085
A61H 3102

US Classification:

13762522

Abstract:

A valving arrangement primarily designed and intended for use in a negative pressure ventilator system. The valve arrangement has a uniquely designed valve that enables the ventilator to perform a number of operations simply by manipulation of a single, one-piece valve member within a valve housing. The valve housing has multiple inlets and outlets and the valve member can be rotated within it to present a variety of pressure cycles to the patient. In the preferred manner of operation, the present invention selectively applies negative and positive pressures to the patient during different portions of the cycle. In this regard, the valve member is structured so that negative and positive pressures are never at the same time delivered to the patient. The valve arrangement is compact and lightweight. It is also functionally superior to prior designs that can only supply whatever pressure is being created by the blower.

International Classification:

G01C 21/34

H04W 4/029
H04W 4/02

Abstract:

Embodiments provide techniques, including systems and methods, for determining matches of requestors and providers based on a dynamic provider eligibility model. For example, a request matching model uses an estimated arrival time for a requestor and estimated travel times for available providers to a pickup location to determine eligible providers for matching to a ride request. The matching model determines those providers that are far enough away from the request location to allow the requestor time to arrive at the pickup location without matching providers that are too far away, causing delay for the requestor and lowering the efficiency of the system by taking provider system resources from other service areas and increasing provider downtime upon matching. Additionally, embodiments provide more efficient matching processing leading to fewer canceled matched requests, fewer requests for a successful match, and fewer system resources necessary to meet requestor demand.

International Classification:

G06Q 10/06
G06N 20/00

Abstract:

This disclosure describes a transportation matching system that manages the allocation of transportation providers by training and utilizing multiple machine-learning models to identify, allocate, and serve specific transportation providers with customized opportunities to relocate the transportation providers between geocoded areas in a geocoded region. For instance, the transportation matching system trains and utilizes an incremental provider model, a provider allocation model, and personalized provider behavioral models as well as a customized provider interface generator to satisfy anticipated transportation requests and improve transportation matching within a geocoded region.
