Abstract: A method for forming sunglass lenses with a predetermined optical gradient, namely a polarized gradient, transmissivity gradient or color gradient in which an ink jet printer is used to print a gradient pattern on an oriented sheet, with the ink jet printer being provided with a dye, in one embodiment a dichroic dye and in another embodiment an iodine dye. The printed oriented sheet is incorporated into a lens to provide the lens with the associated gradient.

Abstract: A method and apparatus for continuously forming a web having a gradient polarization characteristic for use in sunglasses or other optical applications includes drawing a vertically oriented web of molecularly oriented material through a dye bath at an angle to the bath such that the residency time in the bath varies from top to bottom of the web to establish a polarization gradient from 100% at the top of the web to close to 0% at the bottom of the web. This process also creates a minimum transmissivity at the top of the web and a maximum transmissivity at the bottom of the web for permitting viewing displays using sunglasses having lenses cut from the web by viewing a display through the bottom portion of the sunglass lenses.

Abstract: In the manufacture of gradient polarized sunglasses an optical retarder is used in front of a portion of a polarized lens to destroy the linear polarization of incoming light to render that portion of the sunglass lens non-polarized, thus to permit viewing of polarized displays through that non-polarized portion of the polarized sunglass lens.

Abstract: A wireless device-based system provides location-based services by determining the location of the wireless device and arranges for the service and the payment therefor.

Abstract: A pair of sunglasses is provided with a polarized region in the upper portion of the eyeglass lens and a non-polarized region in the bottom portion of the eyeglass lens so as to permit reading of polarized instruments through the non-polarized region. The two regions may be separated horizontally at the halfway point or below the halfway point such that, by tilting one's head upwardly and looking through the non-polarized region, one can readily read the instruments which would appear black through the polarized region due to the cross-polarization. In one embodiment the polarization level is gradually decreased from the top to the bottom of the lens in a polarization gradient in which there is no polarization at the bottom portion of the lens.

Abstract: A wireless phone having an internal GPS-receiver is turned on by an auxiliary switch coupled to a Microwire bus for turning on the phone and the internally carried GPS receiver so that the phone can be made to call a predetermined number and report location. If the switch closure is a result of paging, a phone can be paged to report location whether or not the phone is initially off. This accommodates such applications as Alzheimer patients, truck-tracking, kid-tracking, pet-tracking and in general any application in which a wireless communications device such as a cell phone can be caused to report location, with the phone initially in an off condition. Alternative activations through the closure of specialized switches responsive to airbag deployment, car alarm activation, medical condition alerts, and perimeter violations, provides local activation of the system.

Abstract: A wireless phone based system to accommodate users of wireless phones for providing information as to the location of certain services such as gasoline stations, movie theatres, drug stores, etc., includes the utilization of a GPS receiver and a wireless phone, with the wireless phone adapted to call a predetermined number requesting the desired service and providing the location of the cellular phone. In one embodiment, the GPS receiver is co-located with the wireless phone in a car, with the wireless phone being carried in a handsfree cradle having a number of service-request buttons, such that depression of a service-request button activates the wireless phone through its bus structure to call a predetermined number and provide the identity of the caller along with the caller's location.

Abstract: An audio coupling is provided between a location reporting unit and the microphone of a wireless phone in which location information is provided either by synthesized voice and/or DTMF tones through the audio coupling to the microphone such that the location of the wireless phone can be broadcast on the normal voice channel to a dispatch operation such as a Public Safety Answering Point or to a location-based service provider. The subject interface makes possible the adaptation of any wireless phone to provide location-based information without change to the wireless phone and without any additional infrastructure for the wireless network. The utilization of synthesized speech and/or DTMF tones over the voice channel provides a universality for the system, which can be utilized anywhere where there is both wireless and GPS satellite coverage.

Abstract: A wireless phone is provided with a GPS receiver and a system which is utilized to report the local position of the wireless phone either prior or during to the time of a telephone placed wager, in which the geographic coordinates of the phone are transmitted to the sports bet for verification that the wager is being placed within the geographic limits of the wagering authority. In one embodiment spoofing of the system is prevented by having the wireless phone report the time since last fix such that an individual within the wagering authority's jurisdiction cannot remove himself from the jurisdiction with the location having been remembered, with the wager taking entity processing as valid only those geographic coordinates having a time since last fix of, for instance, ten minutes. Anything over this pre-determined limit is determined to be an invalid wager.
