Abstract:
An air circulation and/or purification device for recirculating air and/or removing contaminants from the air which includes a housing having a top with an opening for air intake and a bottom, a fan contained within the housing, and a plurality of air output vents contained within multiple sides of the housing near the bottom of the housing. The bottom of the housing may include a conical shaped portion extending inward from the bottom of the housing or other structures to assist in expelling air from the housing in at least two different directions. The device may also include one or more filters designed to capture and filter out different types of contaminants.

Abstract:
An optical apparatus (1) for wearing by a human user comprises one or more variable power lenses (4), means (10) for adjusting the power of the variable power lens (4), means (26) for capturing data representative of said adjustments, and means (28) for recording or transmitting the captured data.
Abstract:
A surgical device is provided that includes a jaw portion, having a first jaw in opposed correspondence with a second jaw, the second jaw including a surgical member. The surgical device may include a shaft portion coupled to a proximal end of the jaw portion and at least one motor configured to rotate the jaw portion relative to the shaft portion, to move the jaw portion relative to the shaft portion, move the first jaw relative to the second jaw and move the surgical member within the second jaw. The surgical member may be prevented from moving within the second jaw unless the first jaw is in a closed position relative to the second jaw. Advantageously, the surgical member may be, e.g., a cutting element and/or a stapling element, disposed within one of the jaws.
Abstract:
A surgical device is provided, the surgical device including a first driver for performing a first movement function; a second driver for performing a second movement function; a first rotatable drive shaft configured, upon actuation, to cause selective engagement of one of the first and second drivers with a second rotatable drive shaft, wherein the second rotatable drive shaft is configured to drive the selectively engaged one of the first and second drivers. Third and fourth drivers may also be included. The drivers may function to rotate a shaft portion of the surgical device relative to, and about the longitudinal axis of, a handle; move a jaw portion relative to the shaft portion; move a first jaw relative to a second jaw; and/or move a surgical member within the second jaw.
Abstract:
A system, method, and program product is provided that communicates virus information between a computer that detects a virus in a file (the detecting computer system) and the computer that sent the infected file (the infected computer system). When the infected computer system sends an infected file to the detecting computer system the detecting computer system detects the virus in the infected file, retrieves virus information corresponding to the virus (such as the name of the infected file, the identifier, or name, of the virus, the virus definitions used to identify the virus, and any instructions needed to eradicate the virus), and automatically sends the virus information back to the infected computer system over the network.
Abstract:
A circuit for use with a stator winding of a rotating or linear electrical machine, the stator winding having a number of coils linked by the same number of points of common coupling, includes an electronic commutator circuit having the same number of switching stages, each connected between a respective one of the points of common coupling and first and second main dc lines. Each switching stage includes first and second reverse blocking semiconductor power devices. A voltage clamping circuit includes the same number of clamping stages, each connected between a respective one of the points of common coupling and first and second auxiliary dc lines. Each clamping stage includes first and second diodes and first and second capacitors common to the various clamping stages. A dc to dc converter selectively discharges the first and second capacitors to the first and second main dc lines.
Abstract:
The present invention is directed to a transport package which efficiently maintains payload temperature within a predetermined temperature range during delivery through regions having ambient temperatures outside the desired range. The transport package is used for transporting temperature sensitive materials and thermally protecting the materials from cold and hot ambient temperatures in a manner that does not require a power source or other mechanical devices. Aspects of the invention relate to a temperature maintaining packaging system having an outer container, thermal insulation materials and two or more different phase change materials.

Abstract:
The core (1) of a seat back, which will be upholstered to form the complete back, is a moulded plastics sheet bowed forwardly and with attachment points (12) near top and bottom for securing to a rigid support. The sheet is constructed to be stiffer over its upper portion then over the lower and, when secured, to be able to ripple or alter its curvature between the attachment points. It may have wings (2) inclining forwardly at each side with closed end slots (3) between the wings (2) and the central zone (8) of the core. The wings can be divided into generally horizontal sections carried by integrally moulded transverse ribs (4) spanning the slots (3), the division between sections being by slots (13) or narrow membranes (6). The top of the core may also be divided into side-by-sections, the division being by slots (14) or narrow membranes (11).
