Abstract: A shaving apparatus is provided for shaving hair on a skin surface. The shaving apparatus includes a shaver head having at least one first blade configured to shave hair on a skin surface during displacement of the shaving head in a first direction along the skin surface, and at least one second blade configured to shave hair on the skin surface during displacement of the shaver head in a second direction along the skin surface; and a drive configured to reciprocally slide the first and second blades in an alternating motion between the first direction and the second direction thereby allowing a bi-directionally shaving hair on the skin surface.

Abstract: A catheter, including: (a) an element; (b) an adjustable ring attached to the element such that at least a portion of the element is substantially within the adjustable ring, the adjustable ring having at least a first diameter and at least a second diameter, and the adjustable ring being magnetizable; and (c) a magnetization unit located near a portion of the element, the magnetization unit determining when the adjustable ring has the first diameter and when the adjustable ring has the second diameter.

Abstract: A combat simulation system to be used with models of weapons platforms to simulate firing and target "hits", and to register the firing and the hits, including a remote control, operated by a user, for activating a source of coherent electromagnetic radiation, a target which may be substantially enfilade by the coherent electromagnetic radiation source, an electromagnetic radiation detector situated to receive reflected radiation from the target, and a transmitter for transmitting from the coherent electromagnetic radiation detector to a receiver. According to the present invention, a predator platform including both a coherent electromagnetic radiation source and a coherent electromagnetic radiation detector is maneuvered to a firing position where a target platform is within line of sight of the radiation source. The user activates the radiation source thereby emitting a radiation burst which is reflected from the target platform and picked up by the radiation detector.

Abstract: A catheter, including: (a) an element for transferring a magnetic force; (b) an adjustable ring attached to the element such that at least a portion of the element is substantially within the adjustable ring, the adjustable ring having at least a first diameter and at least a second diameter, and the adjustable ring being magnetizable; and (c) a magnetization unit located near a portion of the element, the magnetization unit regulating the magnetic force transferred by the element for determining when the adjustable ring has the first diameter and when the adjustable ring has the second diameter.

Abstract: A multi-compartment liquid storage container capable of separately storing two or more liquids which may become mixed upon pouring. The storage container comprises a primary container with an internal container of smaller diameter within the hollow of the primary container thus creating an additional storage compartment. Removal of the pull-tab provided on the primary container enables access to the contents of the primary container and the additional storage compartment. In an alternative embodiment, the primary container is provided with a non-removable lift-tab opening and a penetrable foil section is provided in the wall of the internal container. The lift-tab perforates the foil during the opening procedure to provide internal container access. Another alternative embodiment provides an internal container sub-divided by additional compartments, each sealed off from the other by a penetrable foil membrane, allowing for separate storage of a plurality of liquids simultaneously.
