A suturing apparatus for the continuous application of a suture includes a suturing head shaped and dimensioned for attachment to a distal end of a support member. The suturing head includes a track shaped and dimensioned for receiving a needle for movement about the track. A support arm includes first and second lateral arms connected by a central connecting member supporting the track. The support arm includes a longitudinal axis and the track lies in a transverse plane. Angular orientation of the support arm relative to the track is achieved by positioning the transverse plane of the track at an oblique angle relative to the longitudinal axis of the support arm such that operators are provided with improved access to the surgical site. A drive assembly is coupled to the needle for controlled movement about the track.

A helmet construction for protecting a user's head, and the brain within the cranium from impact forces, includes a shell contoured to the shape of the user's head, with cushioning along at least part of the shell interior and a chinstrap. The shell consists of three (or more) discrete panels that are physically and firmly coupled together providing rigid protection under most circumstances, but upon impact the panels move relative to one another, but not relative to the user's head, thereby permitting impact forces to be dissipated and / or redirected away from the cranium and brain within. Upon impact to the helmet, there are sequential stages of movement of the panels relative to each other, these movements initially being recoverable, but with sufficient vector forces the helmet undergoes structural changes in a pre-determined fashion, so that the recoverable and permanent movements cumulatively provide a protective ‘crumple zone’ or ‘shear zone’. The first two stages of protection arise from the design of the fasteners that have the ability to invaginate and collapse within themselves, and their design having a 45 degree angle, which will allow movement of a region of connected panels to translate along the fastener shaft. Both of these movements will be recoverable and provide a ‘functional crumple zone’. The final stage of protection arises from the braking function of the pins, as they are forced from one aperture through to the next, the direction and extent of which is determined by the impact force and direction. This final level of panel movement and protection is not recoverable and thus provides a ‘structural crumple zone’. Finally the fastener size and thickness, together with the thickness of webbing and distance between apertures, functions to provide varying degrees of resistance to impact forces, thus making the helmet design suitable for activities with different levels of impact speed and risk potential.

A method and system for determining a shape of a portion of an air-bearing surface (ABS) of a head residing on a slider are described. The ABS is configured to fly at a fly height from and with a velocity with respect to a disk during normal operating conditions. The method and system include driving at least one heater residing in the head while the slider is substantially at the normal operating conditions with respect to the disk and the fly height. The shape of the portion of the ABS changes in response to the heater(s) being driven. The method and system also include performing Doppler measurements on the slider while the heater is driven. The shape may then be determined based on the Doppler measurements.

A cap-like head backing cover includes a plurality of types of cover components. The plurality of types of cover components include cover main body portions, and connecting means capable of separably connecting and combining the cover main body portions of one of the cover components to and with the cover main body portions of another at least one of the cover components. The cover main body portions of the plurality of types of cover components are connected to and combined with each other by the connecting means, to form the cap-like head backing cover which includes the plurality of types of cover components and is independent. With the helmet having this arrangement, even when a helmet wearer whose head shape is different from that of an average human head is to wear the helmet, the helmet can be matched to the head of the helmet wearer substantially optimally. The helmet size can be not only partially decreased but also partially increased. The cover component at an arbitrary portion of the cap-like head backing cover can be exchanged with a comparatively simple operation. Also, head backing cover can be attached to an impact-on-the-head absorbing liner or the like comparatively easily.

A storage unit for wigs. The unit is attached to a door and hangs from the top of the door. The unit has head-shaped pedestals on which wigs are mounted as well as a ventilated accessory storage container and accessory supporting hooks which are pendently supported from the accessory storage container.
