Appl. No.:

13/465443

Inventors:

Yong Hoon Choi - Palo Alto CA, US

Assignee:

Google Inc. - Mountain View CA

International Classification:

H04M 1/00
H04B 1/04

US Classification:

455574, 4551275

Abstract:

A mobile communication device enables improved connectivity and power management. The device includes a first wireless network interface configured for connection to a first network and a second wireless network interface configured for connection to a second network. The first interface has an active mode of operation and a sleep mode. The device places the first interface in the sleep mode when not needed for communications. An external system such as a messaging server calls the device when it is unable to access the device through the first interface. The second network, which can be a cellular network, handles the call request and transmits a ringing signal to the second interface of the device. A notification handler, upon receipt of the ringing signal, wakes the first interface, permitting normal communications through the first interface. Power management logic can be more pro-active in placing the first interface into the sleep mode.

Appl. No.:

11/163456

Inventors:

Yong Choi - san francisco CA, US

International Classification:

A47B 17/00

US Classification:

312194000

Abstract:

The use of computer case is just to put together computer parts. A computer case needs to be located either on top of the desk, on the side of the desk, under the desk or on the floor. Not only computer desk takes up space but also the computer case is not safe from being stolen. By integrating computer case/chassis with a computer desk, a space-saving issue and parts-being-stolen issue will be resolved. This is a very easy to maintain. It can be unlocked to open the drawer and blow dust. If the system needs to be upgraded then open the drawer swap the parts without going through unplugging, re-plugging or assembling, disassembling hassle. If the system needs to be completely repaired then the entire drawer can be taken out just like the way a regular drawer is moved out. The drawer functions same as computer case but it is integrated with the desk.

Appl. No.:

12/977345

Inventors:

Yong Hoon Choi - Mountain View CA, US

Assignee:

DEUTSCHE TELEKOM AG - Bonn

International Classification:

H04B 7/00

US Classification:

370310

Abstract:

A method for enhancing a data communication throughput associated with an in-vehicle telematics system includes receiving a communication request from the in-vehicle telematics system to perform at least one of a data upload to the Internet and a data download from the Internet, and verifying availability of one or more mobile devices within the vehicle. The maximum capability of a mobile network interface for each of the one or more available mobile devices within the vehicle is determined. When the communication request is for uploading data to the Internet, the data is fragmented into data fragments and distributed to the available mobile devices, whereas when the communication request is for downloading data from the Internet, it is determined for each mobile device which fragment of data is to be downloaded and from which server, and the respective determined fragments are received from each mobile device.

Inventors:

Yong Hoon Choi - Mountain View CA, US

Assignee:

DEUTSCHE TELEKOM AG - Bonn

International Classification:

G01C 21/36

US Classification:

701436

Abstract:

A system for providing an externally visible signal regarding a navigational instruction at a vehicle includes a navigation system, a navigation message sender, a navigation message receiver, and a display system. The navigation system generates and outputs turn-by-turn navigational directions within the vehicle to assist a driver of the vehicle in reaching a given destination location. The navigation message sender receives the turn-by-turn navigational directions and transmits them to the navigation message receiver. The navigation message receiver provides a navigational message to the display system for display in a manner visible outside the vehicle.

Assignee:

DEUTSCHE TELEKOM AG - Bonn

International Classification:

G08G 1/123

US Classification:

340989

Abstract:

A method for assisting a vehicle user in locating a vehicle when parked includes detecting via a mobile device that the vehicle has been placed in a parked state and, in response to detecting that the vehicle has been placed in a parked state, automatically retrieving the vehicle location to the mobile device and recording the vehicle location on the mobile device. The method further entails providing, in response to a request from the user to locate the parked vehicle, instructions to the user to guide the user to the parked vehicle.

Abstract:

A method of selective dry etching of N-face (Al,In,Ga)N heterostructures through the incorporation of an etch-stop layer into the structure, and a controlled, highly selective, etch process. Specifically, the method includes: (1) the incorporation of an easily formed, compatible etch-stop layer in the growth of the device structure, (2) the use of a laser-lift off or similar process to decouple the active layer from the original growth substrate, and (3) the achievement of etch selectivity higher than 14:1 on N-face (Al,In,Ga)N.
