Title: Spray bulb cleaner for digital camera sensors
Inventor: RAHBAR-DEHGHAN FARIBORZ
IPC: B01D46/00
Filed: 2009-10-29
Abstract: A spray bulb cleaner is provided for removing dust from digital camera sensors. The cleaner comprises a compressible yet resilient manually actuatable bulb body defining a deformable wall circumscribing an air enclosure. The bulb wall has an air outlet enabling air outflow from the bulb air enclosure toward ambient air when the bulb is squeezed and becomes deformed. The bulb wall also has an air intake enabling ambient air inflow into the bulb air enclosure. A releasable first one-way valve mounted at the air intake, controls air inflow from ambient air towards the bulb enclosure. A releasable second one-way valve mounted at a tubular nozzle inner end portion controls air outflow from the bulb air enclosure toward ambient air. The nozzle is mounted at to the bulb air outlet. At least a portion of the spray bulb is made from an electrostatically charged ionizing compound for neutralizing a target surface to be dusted by the spray bulb cleaner. A filter member can be mounted adjacent either the first or second one-way valves.

Title: Technique for increasing signal gain
Inventor: CUNNINGHAM JAMES A
IPC: G02F1/01
Filed: 2011-06-01
Abstract: A technique for generating complementary signals for joint transmission involves generating a first signal having a first wavelength and a second signal having a second wavelength. The first signal is modulated with a first modulation to encode data, and the second signal is modulated with a second modulation, which is an inverted version of the first modulation, to encode the same data such that the first and second signals are complementary.  The first and second signals are combined to produce a combined signal in which power attributable to the first signal is interleaved with and substantially non-overlapping temporally with power attributable to the second signal. The combined signal is amplified and then transmitted. The first and second signals can be optical signals at respective first and second optical wavelengths, where the first and second signals are on-off keying (OOK) modulated.

Title: Thermoelectric cooling systems and engines
Inventor: LILKE HARVEY D
IPC: F25B29/00
Filed: 2010-05-26
Abstract: A space efficient system especially suited for use as an entirely self- contained stand-alone unit usable in any of multiple contexts where heating or cooling of a defined-volume or enclosure is required.    Hot or cold sides of the thermoelectric assemblies face toward one another into a central airflow that enters and exits a housing through a top or bottom of the housing that faces into the enclosure, and the opposite sides of the thermoelectric modules face into channels on opposite sides of the central airflow. The channels can be connected to intake and exhaust air through a common end of the housing, or be separated to individually intake and exhaust air at opposing ends of the housing.  Fastener-free mounting of components between insulation shells that cooperate with the thermoelectric assemblies to define the channel boundaries results in tool-free configurability of components for servicing, maintaining, reconfiguring, scaling or customizing of the system.

Title: Liquid shaving preparation
Inventor: PRIETO ALONSO JOSE ANDRES
IPC: A61K8/73
Filed: 2010-07-30
Abstract: The invention relates to a preparation for topical use, consisting of a solution of cosmetic products that allows for use as a shaving product. The invention comprises the use of deodorized alcohol at a concentration equal to or less than 60 wt.-%.
