Abstract: The present disclosure provides a face shield including one or more airstream-deflecting protrusions for deflecting airstream away from the wearer so as to avoid bacteria, virus or any other hazardous materials in the airstream from depositing on the head and/or hair of a wearer. The present disclosure further provides a full face shield including a flexible sheet, and the flexible sheet has a top portion comprising two folding structures located adjacent to lateral edges of the flexible sheet respectively for bending the top portion towards a forehead of a wearer. As the top portion of the full face shield is bent towards a forehead of the wearer through the folding structure, the face, forehead and a large portion of the front skull of the wearer can be protected.

Abstract: Disclosed is an additive composition of a feed for breeding an organism comprising at least one genus of marine algae containing an effective amount of one or more compounds selected from the group consisting of unsubstituted bromophenols and bromophenols substituted with one or more substituents. Also disclosed are a feed containing the additive composition and a method for preparing the feed. Applications of the feed disclosed herein to aquaculture animals can greatly enhance the organoleptic quality of such aquaculture animals.

Abstract: A multipurpose video integrated switch is a design related to a distributor and a sharer for computer video signals. The integrated switch includes a power switch, a plurality of input ports, and a plurality of output ports, and its interior is installed with a control unit connected to the power switch, input ports, and output ports. The control unit is composed of a control circuit, a power circuit, a change-over circuit, a plurality of multiplexer circuits, and a plurality of balanced circuits. Accordingly, multiple video signals can be input simultaneously and transmitted to a plurality of displayers respectively, for achieving a function of video distribution and sharing.

Abstract: A security system is disclosed as including input devices allowing input of access codes into the system; a door operatively associated with the input devices, the closure member being lockable to prevent access through an entrance; and the system is set to perform a first set of function(s) upon receipt of a first pre-defined access code to perform a second set of function(s) upon receipt of a second pre-defined access code; and both the first and second sets of function(s) include at least unlocking the closure member, thus allowing access through the entrance; and the first and second sets of function(s) differ at least in part from each other.

Abstract: A telephony system (100) is disclosed as including a number of telephone sets (116a-116f), a home server (110), a fingerprint scanner (102), a keypad (104), a smart card reader (106), and such other identification devices which are adapted to detect the occurrence of location-related events relating to users of the system (100), and the home server (110) is adapted to assess, on the basis of occurrence of the location-related events, the respective probability of the users being in the vicinity of each of the telephone sets (116a-116f). There is also disclosed a method of operating a telephony system (100), including providing a number of telephone sets (116a-116f); providing a home server (110); detecting the occurrence of location-related events relating to users of the system (100 ); and assessing the respective probability of the users being in the vicinity of each of the telephone sets (116a-116f).

Abstract: A keyboard, which may be made very thin and be suitable for notebook computers or personal digital assistants, has a substantially rigid base plate supported for movement between an extended position and a retracted position but biased to the extended position. The keyboard has a plurality of keys and a switch means associated with each key to register when the key has been pressed. When a key is pressed the base plate moves from the extended position to the retracted position, that movement providing for at least some travel of the pressed key. A sufficient degree of travel can be provided that the keyboard, even in a very thin form, can be used for touch-typing.

Abstract: A keyboard for a miniature computer or other data processing device which permits a standard key spacing to be retained while enabling folding of the keyboard to reduce its overall size for storage or carrying purposes. In another aspect, the thickness of the keyboard when in folded position is reduced in some embodiments by maintaining its keys in depressed positions.
