US Patent:

8643296, Feb 4, 2014

Filed:

Nov 22, 2011

Appl. No.:

13/302991

Inventors:

Cristiano Bazzani - Irvine CA, US
Fabio Gozzini - Newport Beach CA, US
Steven Van Nguyen - Garden Grove CA, US

Assignee:

Mindspeed Technologies, Inc. - Newport Beach CA

International Classification:

H05B 37/02

US Classification:

315209R, 315192, 315210

Abstract:

A system is disclosed to automatically establish proper biasing for light sources in a color mixed projection system having multiple light sources which are active at the same time. Responsive to a feedback signal, a single DC-DC converter generates the bias voltage for the light sources. Comparators compare a headroom signal for each light source to a reference value to generate comparator output signals. The comparator output signals are processed by a channel selector and a digital filter/DAC module. The channel selector controls a switch to selectively provide and combine a headroom signal with an output of the digital filter/DAC module to create the feedback signal. By monitoring each headroom value, the bias voltage is adjusted, based on the feedback signal, until every headroom signal reaches the reference value thereby achieving sufficient biasing for every active light source in the color mixed projection system.

International Classification:

A61B 34/20
A61B 18/14

Abstract:

A method for removing tissues may comprise disposing a tissue resection device at a target tissue site, causing the tissue resection device to resect a core of tissue from the target tissue site, removing the core of tissue from the body, wherein the removing the core of tissue from the body creates a core cavity at the target tissue site. A tracking apparatus may be configured to determine a position of a portion of the tissue resection device in three dimensional space.

Filed:

Jul 16, 2019

Appl. No.:

16/512628

Inventors:

- Somerville NJ, US
Terry Daglow - Houston TX, US
Steven Nguyen - Cypress TX, US

International Classification:

A61B 18/08
A61B 17/34
A61B 18/12
A61B 10/04
A61B 10/02

Abstract:

A method for removing a tissue lesion where an anchor is established with the lesion. A channel is created in the tissue leading to the anchored lesion. A tissue core is created which includes the lesion. The tissue core is ligated, amputated and removed from the channel.

Inventors:

- Somerville NJ, US
Terry Daglow - Houston TX, US
Steven Nguyen - Cypress TX, US

International Classification:

A61B 18/14
A61B 17/3209
A61M 29/02

Abstract:

A kit for removing a tissue lesion includes an anchor for securing a tissue lesion, incision blades for creating an incision in tissue, a tissue resection device for creating a tissue core that includes the tissue lesion and a tissue dilator to help open a channel of sufficient volume to receive the tissue resection device. The tissue resection penetrates tissue, creates a tissue core that includes the tissue lesion and seals and dissects the tissue lesion from surrounding tissue.
