Appl. No.:

09/564960

Shek Fai Lau - Foster City CA

Andrew J. Parker - Sausalito CA

Assignee:

Sharper Image Corporation - San Francisco CA

International Classification:

B01J 1908

US Classification:

42218604, 42218607, 204286

Abstract:

An electro-kinetic electro-static air conditioner includes a mechanism to clean the wire-like electrodes in the first electrode array. A length of flexible MYLAR type sheet material projects from the base of the second electrode array towards and beyond the first electrode array. The distal end of each sheet includes a slit that engages a corresponding wire-like electrode. As a user moves the second electrode array up or down within the conditioner housing, friction between slit edges and the wire-like electrode cleans the electrode surface. Another embodiment includes a bead-like member having a through opening or channel, through which the wire-like electrode passes. As the conditioner is turned upside down and rightside up, friction between the opening in the bead-like member and wire-like electrode cleans the electrode surface. The through channel may be symmetrically formed in the bead-like member, but preferably will be asymmetrical to create a mechanical moment and increased friction with the surface of the wire-like electrode being cleaned.

Abstract:

An electro-kinetic electro-static air conditioner includes a mechanism to clean the wire-like electrodes in the first electrode array. A length of flexible Mylar type sheet material projects from the base of the second electrode array towards and beyond the first electrode array. The distal end of each sheet includes a slit that engages a corresponding wire-like electrode. As a user moves the second electrode array up or down within the conditioner housing, friction between slit edges and the wire-like electrode cleans the electrode surface. The sheet material may be biasedly pivotably attached to the base of the second electrode array, and may be urged away from and parallel to the wire-like electrodes when the conditioner is in use. Another embodiment includes a bead-like member having a through opening or channel, through which the wire-like electrode passes. As the conditioner is turned upside down and rightside up, friction between the opening in the bead-like member and wire-like electrode cleans the electrode surface.

Assignee:

Sharper Image Corporation - San Francisco CA

International Classification:

B08B007/04

US Classification:

134 8, 134 6, 134 42

Abstract:

Methods for cleaning a first group of electrodes contained within an air conditioner are provided. A second group of electrodes within the air conditioner has a cleaning device fastened therewith. The cleaning device engages the first group of electrodes. A method includes removing the second group of electrodes from the air conditioner, and replacing the second group of electrodes back into the air conditioner.

US Classification:

96 29, 96 39, 96 40, 96 51, 96 96, 42218604

Abstract:

An air conditioner device includes a housing, a first electrode disposed in the housing, and a second electrode removably disposed in the housing. The second electrode can be manually removed from the housing and then manually returned to a resting position within the housing. A base member is attached to a bottom portion of the second electrode. An at least partially flexible cleaning member is attached to the base member. The cleaning member frictionally cleans the first electrode when, after being removed from the housing, the second electrode is manually returned to the resting position within the housing.

US Classification:

42218604, 96 29, 96 51

Abstract:

An air conditioner device includes a first electrode array and a second electrode array. A mechanism, that cleans the electrode(s) in a first electrode array, includes a length of flexible insulating material that projects from a base of the second electrode array towards the first electrode array. As a user moves the second electrode array up or down within the conditioner housing, the electrode(s) in the first array are frictionally cleaned.

International Classification:

US Classification:

714744, 714742

Abstract:

A clock generator is disclosed that includes an array of MEMS resonators and a test circuit. The test circuit is operable at start-up to operate one or more of the MEMS resonators to generate test output and analyze the test output to determine whether the operated MEMS resonators meet test criteria. A MEMS resonator is selected that meets the test criteria and its output is used to generate an output clock signal. In addition, the test circuit is operable to analyze the output of the selected MEMS resonator and select a replacement MEMS resonator when the output of the selected MEMS resonator no longer meets the test criteria. The replacement MEMS resonator is then operated and its output is coupled to the output of the clock generator. Thereby, failing and potentially failing MEMS resonators are automatically replaced during operation of the clock generator in its end-use application.
