Abstract: A transcutaneous electric nerve stimulator wet shave razor system. The razor cartridge of this system contains at least two electrodes, preferably the blades, and the system contains sufficient electronics to generate an electrical signal. The electrodes are adjacent to electrical contacts within the razor cartridge and the contacts are connected, via wires, to a signal generation circuit which is connected to one or more batteries. The battery produces a voltage which is to generate a waveform by the signal processing unit. The signal is transmitted to the electrodes and produces an electrical stimulation which affects the skin when it comes into contact with the electrodes. The resulting effect on the skin is a reduction in any discomfort or pain as well as an enhanced tactile experience during the shaving process.

Abstract: The present invention discloses a wet shave shaving system which contains an in situ sensor within the razor cartridge or razor handle. The sensor preferably comprises either a piezoelectric or a piezoresistive material which produces an electrical signal or resistance change when it is strained. In an active feedback system, the signal would be transferred from the cartridge to the razor handle where an electronically-active actuator would extend or retract as necessary to position the cartridge to produce a shave with a constant shave force. In a passive feedback system, the signal would be transferred from the cartridge to the handle where an electronically-activated element, such as an indicator light, would be activated to produce an indication to the user that he or she should reposition the razor to produce a constant shave force.

Abstract: A display rack for displaying boxes, especially boxes containing a plurality of smaller product packages (such as mint packages), comprising a base and a stand having a plurality of openings. Swing arms with lock slots are adapted to extend from two opposing sides of the openings and engage with the product boxes being displayed. The swing arms are moveable inward and outward within a slot in the rack and are such that the arms may be either perpendicular to the vertical axis of the rack, when the arms are adjacent to the back of the rack, or tilted downward when the swing arms are distanced from the back of the rack. Consequently, the engaged product boxes may be located in a level position at the back of the rack (a position which is especially useful for loading, transport and storage) or they may be tipped in a downward position at the front of the rack to prominently display the product.

Abstract: A method for forming a blade having circular apertures with sharpened edges. As opposed to the traditional grinding and deburring method, the present invention utilizes electrochemical machining, electrical discharge machining, electrolytic machining, laser-beam machining, electron-beam machining, photochemical machining, ultrasonic machining, and other non-traditional methods to sharpen and form the blade edges. These manufacturing methods lend themselves to produce unlimited razor blade designs and structures.

Abstract: Razors adapted to support a razor head during shaving while permitting the razor head to move relative to the razor in response to forces encountered during shaving. Preferred embodiments allow a razor head to swivel and also to pivot about an axis normal to a central axis of the razor and normal to an imaginary axis defined by the points of attachment of the razor to a razor head. According to another aspect, an engagement arm comprises a novel slot for controlling the movement of the engagement during shaving, as well as during loading/unloading of a razor head. Embodiments of this invention enable the razor head to maintain optimum shave relation with the skin regardless of the angular differences between the cartridge head, razor handle/grip and shaving motion during shaving.

Abstract: Blade replacement devices for shaving systems which have at least one blade removably connected to a blade support. The blade replacement devices of the present invention advantageously comprise means for receiving a used blade as it is removed from a razor.

Abstract: A removable protective cover for use with razors and razor cartridges. The cover encloses and protects the razor head, which contains the exposed portion of the sharpened blade or blades. Lateral tabs having hooks for engagement with the razor cartridge on one end and a button area on the other end are affixed to both ends of the cover via hinges. When the button area is depressed by opposing forces, in an X-plane, the hook end disengages from the razor cartridge and the cartridge may be removed from the protective cover with minimal or no force in the Y-direction which is perpendicular to the X-plane.

Abstract: Shaving systems having a first support, at least one, and preferably a plurality, of resilient supports, and a plurality of skin-engaging elements movably arranged in spaced relation and supported by the resilient support. The resilient supports normally maintain the movable skin-engaging elements, e.g. blades, guards, and/or cap member, in spaced relation such that the movable, skin-engaging elements are spaced by a first distance, relative to each other, when the skin-engaging elements are in a normal, unbiased position. In one embodiment, when one or more of the skin-engaging elements is acted upon by forces normally encountered during shaving, the resilient supports yield in order to move each of the blades and the cap into a more aggressive position.

Abstract: A razor which actively flexes at least one, and preferably a plurality of skin-engaging elements during shaving to follow the contours of a skin surface. One preferred razor comprises a support and a pair of rotating pivots movably connected to the support. Each rotating pivot contacts separate portions of a razor head. Shaving forces exerted on a first razor head portion in a first direction will cause the rotating pivot to move a second razor head portion in a second direction which is different from the first direction. The razor also comprises means for biasing the rotating pivots to a neutral position. In one embodiment, the support comprises a pivot assembly to which the rotating pivots are connected thereby providing another degree of movement to the rotating pivots relative to the support.

Abstract: A wash station for washing probes which are used with robotic systems. In particular, the wash station is used with robotic systems to provide simultaneous cleaning of both the interior and the exterior of multiple probes employed by the system. The wash station consists of a base, multiple chambers and multiple cylinders. The robotic probe to be cleaned is inserted within one of the cylinders where it is immersed in wash liquid to wash the exterior walls. The cylinders are separated by chambers. The wash liquid is removed from the wash station via a drain located in the base. In a preferred embodiment, independent access for each probe into the wash station is provided. In addition, the wash station provides a large capacity for fluid handling and is constructed such that the station is water tight. In a particularly preferred embodiment, the wash station is constructed from chemically compatible materials which will not be affected by exposure to the materials needed for general chemical synthesis.

Abstract: The present invention is directed to a razor comprising a handle, a razor blade unit having one or more razor blades which can be connected to the front end of the handle, and a connecting device for connecting the razor blade unit to the handle, such that the shaving results are improved for normal shaves as well as for specific applications like medical pre-operation shave. The razor blade unit of the present invention is mounted such that it can swivel relative to the handle about a swivel axis which intersects the cutting edge of the razor blade.

Abstract: A flexible razor head which can flex convexly and concavely during shaving to follow the contours of a skin surface. A blade support comprises a rubber-like material which is compressible and preferably allows the blades to angularly and vertically deflect.
