Abstract: Systems and methods are provided for testing a Device Under Test (DUT) in its working environment. A control computer is coupled to an air compressor and generates a temperature control signal that is provided to the air compressor to generate an amount of hot air or cold air to set the temperature of the DUT's working environment to a desired test temperature. The control computer also generates at least one test signal that is sent to a hardware test element for testing at least one memory component of the DUT at the desired test temperature and obtaining test results. The control computer analyzes the test results to determine a parameter adjustment for the at least one memory element so that it operates in a stable manner at the test temperature.

Abstract: A method for analysing a financial product comprising the steps of: receiving an established portfolio of a user and obtaining a first performance characteristic of the established portfolio; receiving a financial product and obtaining a second performance characteristic of the financial product; comparing the first performance characteristic with the second performance characteristic to determine a diversity rating of the financial product with respect to the established portfolio, wherein the diversity rating is arranged to represent a rating of the diversification of the established portfolio if the portfolio was to include the financial product.

Abstract: Different embodiments of methods and apparatus to produce audio output signals are disclosed. In one embodiment, an ultrasonic speaker outputting ultrasonic signals can be transformed into first audio output signals, which are directional. A non-ultrasonic speaker can output second audio output signals. The embodiment can be configured to output the first audio output signals or the second audio output signals in a vehicle. Another embodiment can be configured to output the first and the second audio output signals together. Yet another embodiment can be configured to be personalized to hearing characteristics of a user, or to depend on sound level of an environment of the user. One embodiment can include a directional speaker attached to a vehicle, with its output steerable towards a user in the vehicle.

Abstract: Different embodiments on hearing enhancement enhancing a user's hearing. For example, a system can include an interface unit with a directional speaker and a microphone. The microphone captures input audio signals that are transformed into ultrasonic signals. The speaker transmits the ultrasonic signals, which are transformed into output audio signals by interaction with air. At least part of the output audio signals is modified to enhance the hearing of the user. Based on the system, the user's ear remains free from any inserted objects and thus is free from annoying occlusion effects. Compared to existing hearing aids, the system is relatively inexpensive. In another embodiment, the system can also be used as a phone. In another embodiment, the system can also access audio signals from other portable or non-portable instruments, wired or wirelessly, such as from home entertainment units, phones, microphones at a conference or speakers at a movie theater.
