Patent CA-2409935-A1 (CA)
Inventor: CHIDLEY EDWARD THOMAS ROBERT
IPC: H01L31/107
Filed: 2001-05-18
Abstract: A horizontal access semiconductor photo detector (2) comprises a horizontal light absorbing layer (8) for converting light into photo-current which layer is configured to confine light within it in whispering gallery modes of propagation. The detector is configured to have a first waveguide portion (18) and a second light confining portion (20, 21) arranged such that the waveguide portion couples light into the detector and transfers light into the light confining portion so as to excite whispering gallery modes of propagation around the light confining portion. The light absorbing layer may be part of the light confining portion or alternatively light can be coupled into the light confining portion or alternatively light can be coupled into the light absorbing layer from the light confining portion by evanescent coupling. The excitation of whispering gallery modes within the light absorbing layer significantly increases the effective absorption coefficient of the light absorbing layer.

Filed: 2003-03-11
Abstract: Using long handled tools such as push brooms, rakes, hoes and other toots such as this the user must bend over while using the tool or use the palm of the hand to push to broom. In this invention with the addition of The Sweep Eeze attached to the end of the broom the user can use the same tools without bending over to push or pull and using the palm of the hand to push the broom. The invention which added to the top of the tool has a swivel handle allowing the user to hold The Sweep Eeze in the upper, lower or any other position in between giving more positions to the user thus limiting repetitive posture and back strain from bending constantly. The Sweep Eeze will also allow persons with back problems to use these tools without having to bend over and allow for more pressure to be applied to the ground with less effort.

Abstract: An apparatus for varying the gain of a fiber optic sensor that non-intrusively senses the strain response of a pipe includes a circumferential strain attenuator that has a annular land portion that mechanically couples the attenuator to the pipe. An annular web extends coaxially from the land portion and has a reduced cross sectional area relative to the land and an annular mandrel portion extends coaxially from the web portion and forms a gap between the pipe and the mandrel. The fiber optic sensor is wound on the circumferential strain attenuator. The web and mandrel cooperate to reduce the strain response of the fiber optic sensor relative to the strain response of the pipe.
