This invention relates to a method and apparatus for securing a cycle pump. The apparatus consists of a C-shaped holding means adjustably adopted so as to be tightly fitted around the pump body. Lips protrude from the C-shaped holding means and are adaptably fitted to receive a locking means. A cover means is fittingly adapted to permit entry of the lips through the cover means, whereupon the shoulder of the cover is forced against the pump head. This causes the pump body and head to become wedged into the cycle frame pegs. Placing a lock through the lips, which contains holes, prevents the pump from becoming unwedged, thus securing the pump.

Introduced here is a display device that comprises a light emitter and a diffractive optical element (DOE) that is optically coupled to receive light from the light emitter and to convey the light along an optical path. The DOE may have an input surface and an output surface parallel to the input surface, where the input surface and the output surface each have a central region and a peripheral region. The DOE further may have optical characteristics such that light exiting the DOE in the peripheral region of the output surface has greater brightness than light exiting the DOE in the central region of the output surface.

A display engine assembly comprises a first imager and a second imager to generate a left image and a right image, respectively, in a head-mounted display device. The left and right images are left and right components, respectively, of a single stereoscopic image. The display engine further comprises an optical waveguide optically coupled to the first imager and the second imager. The optical waveguide is part of a first optical path to convey the left image to a left eye of a user of the head-mounted display device and is also part of a second optical path to convey the right image to a right eye of the user of the head-mounted display device.

An optical light engine includes a pair of lenticular microlenslet arrays (MLAs) located on each side of a polarization converter. Non-polarized light from a source in the engine is focused by the first MLA onto cells of the polarization converter which converts the light to a common state of polarization to increase efficiency and improve contrast in the system. A half wave retarder is included on the polarization converter to change the polarization of any light that is reflected from downstream optical components to match that of the forward propagating light. The second MLA, which includes a relatively large number of microlenslet elements, collects the light from the polarization converter and homogenizes the light to be highly uniform when received at a downstream imaging panel in the light engine such as a liquid crystal on silicon (LCOS) panel.
