Appl. No.:

13/270780

Inventors:

Scott J. Alberhasky - Portland OR, US
David Harper - Battle Ground WA, US

Assignee:

Maxim Integrated Products, Inc. - Sunnyvale CA

International Classification:

H01L 27/088
H01L 21/336

US Classification:

257329, 438268, 257E2706, 257E2141

Abstract:

Semiconductor devices that include a trench with conductive material for connecting a VDMOS device to a LDMOS device are described. The semiconductor devices include a substrate having a first region and a second region, wherein the second region is disposed on the first region. A trench extends from a top surface of the second region to the first region. The semiconductor substrate includes a VDMOS device formed proximate to the top surface of the second region and a LDMOS device that is also formed proximate to the top surface of the second region. The drain region of the VDMOS device is electrically connected to the source region of the LDMOS device by way of a conductive material disposed in the trench.

Abstract:

A tamper detect device is provided to a chassis of a system. The tamper detect device provides a signal when the chassis is opened while at least a part of the system is under power. In one embodiment, the signal is used to produce an immediate warning. In another embodiment, the tamper detect device is incorporated into the system and the warning is audio. In another embodiment, the warning is continually provided until the chassis cover is closed, the system is unplugged, or the tamper detect device is bypassed. In another embodiment, the system is a computer system.

Appl. No.:

16/917614

Inventors:

David Harper - Pomona CA, US

International Classification:

A47J 31/043
A47J 31/20

Abstract:

A beverage brewing device is configured to brew beverages such as coffee and tea. A brewing canister having a filter at a bottom end is held partially within a receiving beaker, and a seal is created between the canister outer surface and the beaker inner surface. Brewing media such as coffee grounds and brewing fluid such as hot water are added to the canister, mixed, and allowed to brew. At a desired time, the receiving beaker is moved relative to the brewing canister so that the brewing canister is partially removed from the receiving beaker. As such, a vacuum is formed between the bottom end of the brewing canister and the receiving beaker. The filter stops brewing media from flowing into the receiving beaker, but the vacuum draws the brewed beverage through the brewing media and filter and into the receiving beaker.
