摘要:
A testing or sampling probe to determine the response of electrical circuits or devices to ultrafast electrical pulses. The probe is detachable from the device being tested. The probe includes a transparent substrate though which optical pulses are focused or directed onto a photoconducting gap. The probe further includes a transmission line associated with the photoconductive gap, and which terminates at a tapered end of the probe in contacts which are placed on the device under test.

A system and method are provided for modifying the effective reading range of an radio frequency identification tag. The tag, a chip-based tag, includes an antenna and a chip in communication with the antenna. The chip includes circuitry including field effect transistors that can modify the effective reading range of the tag by modifying characteristics of the tag including the modulation depth of the backscatter signal, the impedance characteristics of the tag front end electronics, the power consumption characteristics and the threshold power-on voltage of the tag. These characteristics are change either temporarily or permanently in response to commands communicated to the tag from a radio frequency identification reader.

The invention includes various systems, architectures, frameworks and methodologies that can securely enforce a privacy policy. A method is included for securely guaranteeing a privacy policy between two enterprises, comprising: creating a message at a first enterprise, wherein the message includes a request for data concerning a third party and a privacy policy of the first enterprise; signing and certifying the message that the first enterprise has a tamper-proof system with a privacy rules engine and that the privacy policy of the first entity will be enforced by the privacy rules engine of the first enterprise; sending the message to a second enterprise; and running a privacy rules engine at the second enterprise to compare the privacy policy of the first enterprise with a set of privacy rules for the third party.

Methods and apparatus are provided for presenting personalized information to consumers in a retail environment. A personalized price is determined for at least one product that is in physical proximity to the customer. The physical proximity may be determined, for example, by evaluating identifiers, such as RFID tags, associated with each customer and product. A personalized message can be also presented to a customer regarding at least one product that is in physical proximity to the customer. The personalized message can provide, for example, dietary or safety information relevant to the customer and at least one product in the proximity of the customer. The personalized information may be determined based on one or more personalized message rules.

An electro-optical memory cell having a non-volatile programmable refractive index and a method of making. The memory cell includes: a waveguiding structure having a transition metal oxide with oxygen vacancies; a plurality of electrodes for applying an electrical field; and an optical detector for detecting a state of the memory cell. The method includes: fabricating a waveguiding structure having a transition metal oxide with oxygen vacancies; positioning a plurality of electrodes for application of an electric field; arranging the transition metal oxide and the electrodes such that when an electric field is applied, the oxygen vacancies migrate in a direction that has a component which is radial relative to a center of the beam path; applying the electric field thereby programming the refractive index to set a state of the memory cell; and detecting the state of the memory cell using an optical detector.

A method of sharing telematics data for a vehicle with service providers can include receiving the telematics data for the vehicle, where the telematics data dynamically changes over time, and comparing the telematics data with a privacy policy associated with the vehicle. The privacy policy can specify rules for selectively releasing items of the telematics data to one or more service providers. Data items of the telematics data can be selectively provided to the service providers according to the comparing step.

摘要:
An occupant of a cubicle or office can activate transparent partitions to partially or completely enclose a cubicle and/or office to minimize noise, optimize privacy, lighting, air flow and temperature. This transparent partition is coated with a thin layer material connected to electrodes. Once the occupant decides that changing working conditions (e.g., minimize noise, optimize privacy, adjust lighting, air flow and/or temperature) is needed, the occupant can activate the thin transparency control layer by appropriate electronic control. Movable parts of the partitions may also be adjusted. The transparent partitions may be made darker or opaque. Movable partitions may be used to provide optimized privacy, noise level, lighting, air flow and temperature control. Conversely, the partitions may be made transparent and movable sections retracted to permit greater worker-to-worker interaction.
