Patent number: 11955117Abstract: A system and method are provided for analyzing and reacting to interactions between entities using electronic communication channels. The method includes receiving, via the communications module, data captured from a conversational exchange between a first entity communicating with a second entity using an electronic communication channel. The method also includes analyzing the captured data to detect an indication that the first entity is or was distracted during the conversational exchange, is or was disinterested in a portion of the conversational exchange or missed the portion of the conversational exchange. The method also includes determining based on the indication an action to address the distraction during, disinterest in, or missing of, the portion of the conversational exchange; and providing, via the communications module, an automated message to at least one of the first entity and the second entity for executing the action.Type: GrantFiled: May 27, 2021Date of Patent: April 9, 2024Assignee: The Toronto-Dominion BankInventors: Bridget McDermid, Brian Bellwood, Natalie Thien Huong Cornwall, Jeffery David True, Ryan Wall, Stella Pui Kwan Chan, Venetia D'Souza, Christopher Michael Arthur Caravan, Pranavan Premathas, Sahifa Habib Qazi, Mah Noor Siddiqui, Joe Moghaizel, Jonathan K.

Patent number: 11800613Abstract: Lighting devices and methods utilize multiple independently controllable groups of solid state light emitters of different dominant wavelengths, with operation of the emitter groups being automatically adjusted by processor(s) to provide desired illumination. Operation of the emitter groups may be further affected by sensors and/or user input commands (e.g., sound patterns, gesture patterns, or signal transmission). Operation may be adjusted to compensate for presence, absence, intensity, and/or color point of ambient or incident light. Presence of five or more groups of solid state light emitters provide desirable luminous flux, color point, correlated color temperature (CCT), color rendering index (CRI), CRI R9, and luminous efficacy characteristics of aggregate emissions over a wide range of CCT values, and may permit adjustment of vividness (e.g., relative gamut) and/or melatonin suppression characteristics for a selected color point or CCT.Type: GrantFiled: September 3, 2021Date of Patent: October 24, 2023Assignee: IDEAL Industries Lighting LLCInventors: Antony Paul van de Ven, Chin Wah Ho, Wai Kwan Chan, Charles M.

Patent number: 10900653Abstract: Solid state light engines are disclosed that emit a bright, non-symmetrical emission pattern, with a relatively high luminous flux and from a relatively small area. The light engines can be used in many different types and sizes of light sources, with some embodiments providing a light quantity, quality and distribution similar to conventional J-type Halogen light sources. The light engines are arranged with integral power supplies and heat management features that allow for the engines to provide high emission intensities while generating significantly less heat at the light source. This can result in significantly higher efficiency and greater life space. In some embodiments, the light can perform similarly to a halogen J-type Lamp 80 mm light tube, while generating similar or greater amounts of light. The light engines according to the present invention provide the capability to be used in low profile light fixtures.Type: GrantFiled: November 1, 2013Date of Patent: January 26, 2021Assignee: Cree Hong Kong LimitedInventors: Antony Van De Ven, Wai Kwan Chan, Chin Wah Ho

Patent number: 10421157Abstract: A method of forming an electrode structure for a capacitive touch sensor in a first transparent conductive layer (19) which is located on a first side of a glass substrate (5) on the second side of which is a color filter layer (11,12,13) over-coated with a transparent non-conductive layer (15) and a second transparent conductive layer (7), by a direct write laser scribing process using a pulsed solid state laser (22), the laser wavelength in the range 257 nm to 266 nm and a pulse length in the range 50 fs to 50 ns so grooves (21) are formed in the first transparent conductive layer (19) to electrically isolate areas of the first transparent conductive layer (19) on opposite sides of each groove (21). This selection of wavelength and pulse length enables the grooves (21) to be formed with substantially no damage to the underlying color filter layer (11, 12, 13), the transparent non-conductive layer (15) or the second transparent conductive layer (7) on the second side of the glass substrate (5).Type: GrantFiled: February 14, 2014Date of Patent: September 24, 2019Assignee: M-SOLV LTD.Inventors: Yuk Kwan Chan, Camilo Prieto Rio

Patent number: 10203817Abstract: A method of forming an electrode structure for a capacitive touch sensor in a transparent conductive layer located on a transparent non-conductive layer which is located on a color filter layer by a direct write laser scribing process using a pulsed solid state laser, the laser wavelength, pulse length and beam profile at the substrate being selected to have a wavelength in the range 257 nm to 266 nm, a pulse length in the range 50 fs to 50 ns, and a top hat beam profile having a uniformity of power or energy density between a value (Emax) and a minimum value (Emin) of less than 10%, where uniformity is defined as (Emax?Emin)/(Emax+Emin). 1 Grooves can thus be formed in the transparent conductive layer to electrically isolate areas of the transparent conductive layer on opposite sides of each groove with substantially no damage to the transparent non-conductive layer or the color filter layer beneath the transparent conductive layer.Type: GrantFiled: February 14, 2014Date of Patent: February 12, 2019Assignee: M-SOLV LTD.Inventors: Camilo Prieto Rio, Yuk Kwan Chan
