Assignee:

SYNAPTICS INCORPORATED - Santa Clara CA

International Classification:

G06F 3/033

US Classification:

345158

Abstract:

An input device and a method for providing an input device are provided. The input device assembly includes a base, a sensor support, and a scissor mechanism attached to the base and the sensor support. The scissor mechanism allows for only substantially uniform translation of the sensor support towards the base in response to a force biasing the sensor support substantially towards the base.

Appl. No.:

8/017805

Inventors:

Sang I. Han - Northbrook IL

Assignee:

Han Medical Designs, Inc. - Northbrook IL

International Classification:

A61M 500

US Classification:

604110

Abstract:

An improved device for removing used needles from reusable syringes is provided. The device may be operated using only one hand and requires a single downward force applied to the syringe body by the health care worker. At the lower end of the downward stroke, the collar of the needle has been twisted off the syringe body and is automatically deposited into the receptacle for used needles. The health care worker releases the force and the apparatus automatically resets itself to receive another used needle. The device has few parts and may be assembled easily.

Appl. No.:

8/066283

Inventors:

Sang I. Han - Northbrook IL

Assignee:

Han Medical Designs, Inc. - Northbrook IL

International Classification:

B26B 1100

US Classification:

7158

Abstract:

A combination ring cutting and removing device is provided for use by medical personnel for cutting and removing rings from injured or swollen fingers. If the finger that carries a ring is badly injured, the swelling of the injured finger often precludes the removal of the ring. The ring must be cut in order to restore circulation to the swollen finger. The combined ring cutting and ring removing device is provided in the form of a plier-type cutting device with a built in means for prying the cut ring apart so the ring can be removed from a swollen finger. The device may also be used for non-medical applications that require a cutting action followed by a prying or separating action.

Appl. No.:

7/596746

Inventors:

Sang In Han - Glenview IL

International Classification:

A61M 3500
B67D 542

US Classification:

604289

Abstract:

A disposable pressure wound irrigation device is provided having a reservoir of cleansing solution disposed therein and a pressure chamber for providing a force upon the reservoir such that a liquid stream of cleansing solution is expelled at a constant pressure therefrom. Preferably, the propellant chamber will be provided with a regulator valve fitted within the pressure chamber for constantly monitoring the pressure which urges the chamber against the reservoir. An aimable outlet nozzle is provided through which the cleansing solution is expelled, the nozzle directing the flow of the cleansing solution to the wound surface. A release valve is further provided in order to selectively couple the nozzle with the reservoir, such that the cleansing solution may be evacuated therefrom through a passageway formed by a depression of the valve.

International Classification:

G06K 9/62
G06F 21/60

Abstract:

One embodiment provides for a method for evaluation of an artificial intelligence (AI) service, the method includes partitioning, by a processor, data into in-domain data and out-of-domain data. The processor defines held-out data from both of the in-domain data and the out-of-domain data for evaluation by each of domain and sub-domain based on building a taxonomy of both domains and sub-domains for the AI service. The held-out data is excluded from training data used for training the AI service. The processor further determines distribution underlying performance metrics for the held-out data using bootstrap validation processing. The processor also determines performance guarantees for multiple settings conditioned on multiple characteristics of an application scenario for the held-out data of the taxonomy based on the underlying performance metrics.

The processor defines held-out data from the in-domain data and the out-of-domain data for evaluation by domain and sub-domain based on building a taxonomy of domains and sub-domains for the AI service. The processor further determines distribution underlying performance metrics for the held-out data using statistical processing. The processor also determines performance guarantees for multiple settings conditioned on multiple characteristics of an application scenario for the held-out data of the taxonomy based on the underlying performance metrics. The processor further provides confidence intervals based on the performance guarantees.

International Classification:

G06F 3/044
G06F 3/041

Abstract:

This disclosure generally provides an input device, electronic systems and processing system for touch sensing. In one example, an input device for touch sensing includes receiver electrodes and transmitter electrodes arranged in transmitter and receiver electrode columns. Each transmitter electrode within each transmitter electrode column is paired with two adjacent receiver electrodes of a first column of the receiver electrode columns. A first plurality of traces couple a first group of receiver electrodes in the first receiver electrode column, the first plurality of traces not passing between the transmitter and receiver electrodes of the first transmitter and receiver electrode columns. A second plurality of traces coupled a second group of receiver electrodes in the first receiver electrode column, the second plurality of traces passing between one of the transmitter electrodes of the first transmitter electrode column and one of the receiver electrodes of the second group of receiver electrodes.

Abstract:

Techniques for providing plant growth lights with improved performance and cost are discussed herein. Some embodiments may provide for a light emitting diode (LED) flip chip chip-on-board (COB) module for optimizing plant growth, including: a circuit board; ultraviolet (UV) LED flip chips connected to the circuit board; a royal-blue phosphor or fluorescent layer covering a first portion of the UV LED flip chips; and a deep-red phosphor or fluorescent layer covering a second portion of the UV LED flip chips. The royal-blue phosphor or fluorescent layer absorbs UV light generated by the first portion of the UV LED flip chips and converts the UV light into broad-band light in royal-blue spectrums. The a deep-red phosphor or fluorescent layer absorbs UV light generated by the second portion of the UV LED flip chips and converts the UV light into broad-band light in deep-red spectrums.
