Abstract: Described herein are a system and techniques for enabling biometric authentication without exposing the authorizing entity to sensitive information. In some embodiments, the system receives a biometric template from a user device which is encrypted using a public key associated with the system. The encrypted biometric template is then provided to a second entity along with a biometric identifier. Upon receiving a request to complete a transaction that includes the biometric identifier and a second biometric template, the second entity may encrypt the second biometric template using the same public key associated with the system and perform a comparison between the two encrypted biometric templates. The resulting match result data file is already encrypted and can be provided to the system to determine an extent to which the two biometric templates match.

Abstract: Embodiments of the invention involve using biometric templates to wirelessly authenticate individuals. In one embodiment, a mobile device may generate a first biometric template and a first public value from a first biometric sample of a user and generate a first cryptographic key by passing the first biometric template to a fuzzy extractor's generate function. An access device may generate a second biometric template from a second biometric sample of the user, generate a second secret cryptographic key by passing the second biometric template and the first public value to the fuzzy extractor's reproduce function, encrypt the second biometric template with the second secret cryptographic key, and broadcast the encrypted template to a plurality of nearby mobile devices including the mobile device. If the mobile device is able to decrypt the encrypted template with the first cryptographic key, the access device can associate the user with the mobile device.

Abstract: A closure (20, 2GA, 2GB) is provided for a system with an opening. The closure (20, 20A, 20B) has a body (24, 24A, 24B) with an outer end (32, 32B) and a through passage (30, 3GB) for communicating with the system opening. The body (24, 24A, 24B) has a membrane (60, 60B) mitially occluding the through passage (30, 30B). The closure (20, 20A, 20B) has a lid (26, 26A. 26B) to accommodate movement relative to the body (24. 24A, 24B) between a closed position restricting access to the through passage (30, 30B) and an open position permitting greater access to the through passage (30, 30B). The body (24, 24A, 24B) thither has a separation member (70, 7GB) that can be engaged by a user to separate at least a part of the membrane (60, 60B) from the body (24, 24 A. 24B).

Abstract: The invention is a bicycle rack that attaches to the tongue of a tent camper. The bicycle rack is attached to the tent camper with two plates that are placed on the top and bottom of the tongue. Then a bolt is placed through openings in both plates and tightened to the plates against the tongue of the tent camper. The bicycles are supported by posts attached to the top plate over the top of the tongue. The two vertical posts are braced at the top. Extending from the two vertical posts are horizontal rods that the bicycle is placed over to ride upon the rack. Bicycles can be placed on both sides of the rack. When it is necessary to raise the tent camper, the bicycle rack can be moved into a horizontal position so that it will not affect the raising of the tent camper.

Abstract: A system for locating a feature of an object disposed in a frame includes a spot projector for projecting a spot in the general vicinity of the feature and an imaging device with a limited field of view. The spot projector is a precision device which projects the spot towards a preselected location on the frame. When the spot and the feature are in the field of view of the imaging device, the absolute location of the feature is determined from its selective distance to the spot. Provisions are also made for determining depth or relief information about the object.
