A system designs a thin and relatively flat microwave focusing lens that can produce multiple simultaneous beams, using readily-available isotropic dielectric materials, and having a gradient-index (GRIN) profile. The design optimizes the lens to achieve beam scanning and/or multiple beams over a wide field of regard (FOR) with broad bandwidth and a very short focal length compared with conventional lenses. The lens can be used individually or as an element in a more complex antenna having multiple lenses in various orientations that are independently switched, selected and/or excited simultaneously as elements in a phased array. The antenna terminal incorporates such lens into an array of lenses along with one or more feeds to produce single or multiple beams covering a broad field of regard for such applications as satellite communications on-the-move, cellular, broadband point-point or point-multipoint and other terrestrial or satellite communications systems. The lens and array design support multiple simultaneous independently steerable beams as well as null placement for interference cancellation.

A housing for microelectronic devices requiring an internal vacuum for operation, e.g., an image detector, is formed by tape casting and incorporates leads between interior and exterior of the housing where the leads are disposed on a facing surface of green tape layers. Adjacent green tape layers having corresponding apertures therein are stacked on a first closure member to form a resulting cavity and increased electrical isolation or channel sub-structures are achievable by forming adjacent layers with aperture dimension which vary non-monotonically. After assembly of the device within the cavity, a second closure member is sealed against an open face of the package in a vacuum environment to produce a vacuum sealed device.

The LED lighting device includes a tubular housing, a light emitting unit, and a reflector. The tubular housing has an accommodating space. The light emitting unit is disposed in the accommodating space and has a plurality of light emitting diodes. The reflector is disposed in the accommodating space and has a wing-shaped reflecting portion. The reflecting portion faces the light emitting unit for reflecting the light source emitted from the light emitting diodes to the lateral directions of the tubular housing. As a result, the light source can be converted to a specific direction. Compare to the fluorescent lamps, the present invention has higher illumination efficiency and a longer operating life. The volume of the lamps and the cost are saved.

A suction accumulator for refrigeration or air-conditioning system use, especially for automotive air conditioning system use, which comprises a “pickup tube” to withdraw liquid from a reservoir of the accumulator to return oil to the compressor. The accumulator has a deflector with an outlet tube, to help ensure that fluid does not flow directly from the inlet opening to the outlet opening of the accumulator. The relatively narrow second portion of the outlet tube is closer to the outlet opening than the first portion. The pickup tube is secured in communication with the relatively narrow second portion and optimises the oil return function, minimises restriction to refrigerant flow, maximises effective and actual reservoir volume, and minimises the amount of liquid delivered to the compressor at switch-off. Incorporating an electric heating element or a heat exchanger for engine coolant or exhaust allows the accumulator of the present invention to function as the evaporator when the refrigeration system is used in heat pump mode for heating applications.

A concentrated non-aqueous cleaning solution having a long shelf life includes an ester and an anhydrous surfactant. The ester is the active ingredient for dissolving graffiti, grease and other contaminants. The ester can be one of or a mixture of dimethyl glutarate, dimethyl succinate, dimethyl adipate, ethyl lactate, and a methyl ester extracted from soybean oil. The anhydrous surfactant is preferably alcohol ethoxylate. The ester in the concentrated solution does not degrade into an acid and alcohol as long as the solution is not mixed with water. This allows the concentrated solution to be shipped and stored and remain efficacious. The concentrate can be diluted with water immediately prior to use. Diluting before use makes the graffiti cleaner less expensive and prevents damage to sensitive surfaces but does not provide long enough time for the ester to degrade.
