US Patent:

20110280654, Nov 17, 2011

Filed:

Jul 25, 2011

Appl. No.:

13/190139

Inventors:

Ryan P. Selby - Palo Alto CA, US
Neil P. Everson - Woodinville WA, US
Paul A. Robertson - Bothell WA, US

Assignee:

LeMond Fitness, Inc. - Woodinville WA

International Classification:

F16B 2/18

US Classification:

4033745

Abstract:

An exercise device including at least one positionable component configured to be positioned by a user. The exercise device includes a frame to which a collar is mounted. The positionable component includes a member that is slidably received within the collar and may be positioned by sliding the member to a selected position. A locking assembly is coupled to the collar and is operable to lock the member in a selected position within the collar, to release the member from the locked position, and when released, to allow the member to slide within the collar. The locking assembly includes a cam pivotably mounted to the collar and a cam follower assembly selectively biased by the cam against a portion of the member disposed inside the collar. The locking assembly also includes a pair of engagement members disposed inside the collar opposite the cam against which the cam biases the member.

International Classification:

H01L 21/66
H01L 21/67
H01L 21/683

Abstract:

A semiconductor substrate support for supporting a semiconductor substrate in a plasma processing chamber includes a heater array comprising thermal control elements operable to tune a spatial temperature profile on the semiconductor substrate, the thermal control elements defining heater zones each of which is powered by two or more power supply lines and two or more power return lines wherein each power supply line is connected to at least two of the heater zones and each power return line is connected to at least two of the heater zones. A power distribution circuit is mated to a baseplate of the substrate support, the power distribution circuit being connected to each power supply line and power return line of the heater array. A switching device is connected to the power distribution circuit to independently provide time-averaged power to each of the heater zones by time divisional multiplexing of a plurality of switches.
