Abstract: A shaving preparation that undergoes a change discernible to the user when the hair to be shaved has had time to absorb water and soften, when the shaving preparation has been sufficiently hydrated, after a period of time in which proper hair hydration would normally be expected to have been achieved, or any combinations thereof. Shaving preparations of this type advantageously alert the user when at least one desired shaving condition exists.

Abstract: A shaving assembly for simultaneously applying a shaving preparation and removing hair in a single step includes a base having an upper end, a lower end and a hollow space between the upper and lower ends, whereby the hollow space defines an opening at the upper end of the base. The shaving assembly includes a receiver for a razor, such as a cartridge receiver for a razor blade cartridge, that is connected with the base and that is disposed at the opening at the upper end of the base. The cartridge receiver has a perimeter and the opening at the upper end of the base completely surrounds the perimeter of the cartridge receiver. The hollow space of the base is adapted for containing a shaving preparation, such as a soap cake, a liquid soap, shaving cream or a body wash and may be combined with skin beneficial ingredients and/or scent.

Abstract: The present invention is directed to a wet shaving system having an electronic indicator for indicating when the blades are becoming dull and in need of replacement. As razor blades dull, the user must exert greater force during shaving to achieve a satisfactory shave. Upon exertion of this extra force, a piston which is adjacent to the blades moves away from the blades in response to the increased forces encountered by the blades during shaving. Upon moving a sufficient distance, the piston pushes into an electronic device, such as a potentiometer, which initiates a signal processing circuit which in turn activates an indicator, such as a light-emitting diode. The activation of the indicator is a signal to the user to replace the blades.

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 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: A method of forming an n-p junction in a body (44, 44a, 44b) formed of Group II and Group VI elements. The body (44, 44a, 44b) initially is of p-type conductivity characteristic, and a dry reactive etching process is employed for forming a via (60, 60a, 60b) in the body by a chemical reaction which is also effective to type convert a portion of the body adjacent the via. An n-doped region (64, 64a, 64b) is thereby formed within the body around the via and between the via and the remaining, p-doped region of the body, thereby defining an n-p junction. In one embodiment, the body is mounted on an electrical device (50, 50a, 50b) having an input contact pad (58, 58a, 58b), and an electrically conductive layer (62, 46a, 90) is formed in connection with the contact pad and the n-doped region adjacent the via.
