John Qiang Huang - Irvine CA, US

Assignee:

Wispry, Inc. - Irvine CA

International Classification:

H01G 5/16
H01G 7/06
H01G 5/00

US Classification:

361290, 361281, 361287

Abstract:

Micro-electro-mechanical system (MEMS) variable capacitors and actuation components and related methods are provided. A MEMS variable capacitor can include first and second feed lines extending substantially parallel to one another. Further, MEMS variable capacitors can include first and second capacitive plates being spaced apart from the first and second feed lines. The first and second capacitive plates can be separately movable with respect to at least one of the first and second feed lines for varying the capacitance between the first and second feed lines over a predetermined capacitance range.

John Huang - South San Francisco CA, US

Assignee:

PentagonLight - South San Francisco CA

International Classification:

F21L 4/00

US Classification:

362202, 362109, 362119, 362253, 362208

Abstract:

A self-defense flashlight includes sharp edges positioned around the head end. A sharp edge protector can be positioned so as to surround and protect the sharp edges, when the flashlight is not being used for self-defense purposes. When needed, the sharp edge protector can be moved so as to expose the sharp edges, allowing the flashlight to be used as a weapon. The protectable sharp edges can also be positioned around the tail end of the self-defense flashlight.

International Classification:

H04J 3/06

US Classification:

370519, 370252, 370350

Abstract:

A communication system comprises a mobile switching center configured to determine a first delay metric for first traffic on a first path from the mobile switching center to a first node, and determine a first delay differential based on the first delay metric and a second delay metric for second traffic on a second path from the mobile switching center to a second node. The communication system also comprises the second node having a delay buffer configured to delay the second traffic based on the first delay differential.

US Classification:

514 76, 514 97, 514 36, 514 37, 514300

Abstract:

Biodegradable polymeric microparticle compositions containing one or more active agents, especially those useful for treating or preventing one or more diseases or disorders of the eye, and methods of making and using thereof, are described. In a preferred embodiment, the microparticle compositions contain one or more active agents useful for managing elevated intraocular pressure (IOP) in the eye. Relatively hydrophilic, and preferably carboxylated, polymeric materials such as PLGA are used for a drug such as timolol maleate, which is relatively water soluble, to increase drug loading. Higher molecular weight polymers, as well as the ratio of LA (which has a longer degradation time, up to one to two years) to GA (which has a short degradation time, as short as a few days to a week), are used to provide release over a longer period of time.

Abstract:

The present invention provides a method of stimulating dendritic cells, comprising contacting the dendritic cells with methionine enkephalin. The present invention also provides methods of enhancing an immune response to an antigen in a mammal. In a first method, dendritic cells are isolated from the mammal. The dendritic cells are then contacted with methionine enkephalin for a time sufficient to stimulate the cells. Next, the stimulated dendritic cells are contacted with the antigen of interest for a time sufficient for the cells to process the antigen. The dendritic cells are then injected into the mammal. The dendritic cells may be injected into the animal either on their own, or along with methionine enkephalin and/or the antigen. In a second method, the antigen of interest and methionine enkephalin are administered to the mammal. The present invention also provides compositions for administration to a mammalian subject having a tumor.

International Classification:

US Classification:

Abstract:

A rechargeable flashlight uses induction for charging, and thus does not utilize external contacts. The flashlight is cylindrically shaped, and has a secondary coil wrapped around a portion of the cylindrical body. The flashlight is placed within a ring shaped charger with a primary coil, such that the primary coil is wrapped around the secondary coil. This greatly maximizes the amount of interfacing area between the two coils, without adversely affecting the reflector design. This allows for the charging of a high powered flashlight, without requiring the flashlight to have a disadvantageously sized or constructed head. Furthermore, the primary coil of the charger can advantageously serve as a mechanical support for the flashlight.

US Classification:

514 2

Abstract:

The present invention provides a method of decreasing side effects in a human or animal cancer patient due to radiation therapy or chemotherapy. With this method, methionine enkephalin is administered to the patient at least one time per week for a first time period, where the first time period is at least three weeks. In one embodiment, the first time period is one or two months. Methionine enkephalin is then administered to the patient one time per month for a second time period, where the second time period is at least one month, and where the second time period is consecutive to the first time period. In one embodiment, the total term of methionine enkephalin treatment is at least six months. Methionine enkephalin may be administered to the patient at the same time as, before, or after administration of radiation or chemotherapy.
