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.

According to an aspect, there is provided a computer-implemented method (100) for monitoring usage of a cutting element of a hair cutting device, the method comprising: receiving (102) pressure data indicative of a pressure applied by a cutting element of a hair cutting device on a surface at intervals during a cutting event; storing (104) the received pressure data in a storage device; estimating (106), based on pressure data stored in the storage device in relation to the cutting event and on pressure data stored in the storage device in relation to one or more previous cutting events, a level of wear of the cutting element; and providing (108) an indication of the estimated level of wear for presentation to a recipient.

A handle for a shaving razor in which the handle comprises a frame and a movable member assembly operably coupled to the frame such that the frame is disposed between the movable member assembly and where the movable member assembly portions are configured to move both above and below the frame. The movement can be linear or rotational. The movable member assembly comprises one or more springs. The first member and the second member are coupled together through said rigid member. The rigid member can include a rigid member platform which has a width to thickness ratio from about 7 to about 60.

A shaving razor cartridge having a housing with a guard, a cap, and one or more blades located between the guard and the cap. The guard is positioned in front of the one or more blades and the cap is positioned behind said one or more blades. A heating element is mounted to the housing for transferring heat during a shaving stroke. The heating element has a skin contacting surface. An insulating member is positioned beneath the skin contacting surface for delivering heat to the heating element. An electrical circuit is configured to deliver energy to the insulating member. The electrical circuit includes a control circuit for temperature regulation. A power source in communication with the electrical circuit. A plurality of spaced apart thermal sensors are mounted to the insulating member and positioned below the skin contacting surface. The thermal sensors measure the temperature of the heating element and are in communication with the control circuit.

A razor handle including a handle body and a mechanism for tracking usage of a razor blade or razor blade cartridge. The tracking mechanism includes means to identify a unique razor blade cartridge attachment to the handle body and electronic circuitry disposed within the handle body for automatically tracking razor blade or razor blade cartridge use. The collected data is then sent out to and stored at a remote server.

A shaving razor system with a handle having an elongated gripping portion with a proximal end portion and a distal end portion. A connection base is mounted to the proximal end portion of the handle. A heater bar is operably connected to a power source positioned within the handle. The heater bar is joined to the connection base. A removable razor cartridge having a housing with a guard, a cap and at least one blade mounted to the housing between the guard and the cap. An interconnect member fixed to the housing and having a handle mounting surface releasably engaged with a corresponding surface on the connection base.

Handle is provided for battery operated razors. In some implementations, the handle includes a simple, efficient mechanism for both securing a battery cover to the handle of a razor and at the same time providing a high reliability electrical contact between the battery and electronics of the razor. The mechanism includes a closing system, including a first conductive component slidably attached within the battery cover and biased toward a predetermined axial position, and a second conductive component secured to the interior wall of the grip portion. The first conductive component is configured to interact with the second conductive component and move axially within the battery cover during engagement of the battery cover with the grip portion.

The present disclosure relates to a smart straight razor. Particularly, the smart straight razor includes motor-driven assemblies coupled to a blade tray assembly that is controlled by a blade controller for safely loading, ejecting, and precisely adjusting exposure and/or tilt of a razor blade.
