A mirror assembly for a vehicle includes a mirror element having at least one substrate that has a forward surface and a rearward surface. The mirror element comprises at least one substantially reflective metallic layer sandwiched between a respective pair of substantially transparent non-metallic layers. Each of the substantially transparent non-metallic layers and the substantially reflective metallic layer have a selected refractive index and a selected physical thickness such that the reflective element is selectively spectrally tuned to substantially transmit at least one preselected spectral band of radiant energy therethrough while substantially reflecting other radiant energy. A radiant energy emitting element is disposed at or near the rearward surface of the at least one substrate. The radiant energy emitting element is configured to emit radiant energy with a peak intensity within the at least one preselected spectral band.

Disclosure herein concerns a method that includes illuminating a user's eye with an illumination source in a head-worn display, capturing an image of the user's eye with an eye camera in the head-worn display, wherein the image includes an eye glint produced by light from the illumination source that is reflected from a surface of the user's eye, determining a size of an eye glint in the captured image, and identifying a change in focus distance for the user's eye in correspondence with a change in the size of the eye glint.

A power tool having a receptacle for securing a tool to a drive shaft thereof is disclosed. The receptacle comprises a receiving opening, preferably being arranged on the tool. The receiving opening engages a securing section preferably being provided in a raised fashion on the drive shaft of the power tool, thereby effecting a positive fit. The securing section comprises a plurality of rounded tips arranged at even radial distances from said longitudinal axis, at angular intervals between each other, each rounded tip having a pair of lateral flanks extending from a common apex toward an intermediate section connecting lateral flanks of a pair of adjacent rounded tips. Preferably the receiving opening comprises a number of rounded tips which is twice the number of rounded tips provided on the raised section.

An object of the present invention is to provide a touch panel having a press detection function, which makes it possible to suppress degradation of visibility of a display unit of a display device even when mounted on an electronic device, and also to improve a pressure measuring precision. For this purpose, the touch panel of the present invention includes a first substrate, a second substrate disposed oppose to the first substrate, a pair of electrodes disposed on either one of opposed surfaces of the respective substrates or disposed separately on both of the surfaces, pressure sensitive ink members disposed with a gap from at least one of the pair of electrodes, each of the pressure sensitive ink members having an electrical characteristic varied by a pressing force applied thereto, and a gap retaining member for bonding the first and second substrates to each other and for retaining a gap between each of the pressure sensitive inks and at least one of the pair of electrodes, wherein the pair of electrodes are disposed in a frame shape along an edge portion of the first or second substrate, and the pressure sensitive ink members are scattered along the edge portion of the first or second substrate so that, when the first or second substrate is deformed upon an application of an external force, at least one of them is made in contact with both of the pair of electrodes so as to make the two electrodes conductive to each other.
