Abstract: A method includes sequentially generating fragment records for a user device according to fragment generation rules specifying that each subsequent fragment record be generated for user device events that occur within a defined period of time. Each fragment record includes event data for a series of user device events and includes a fragment ID generated using a non-deterministic ID generation algorithm. The method includes generating an ID-fragment record associating a chain ID with the fragment IDs. The chain ID is associated with device IDs that identify the user device. The method includes removing associations between the chain ID and fragment IDs according to removal parameters indicating that associations be removed based on an age of the fragment records. The method includes generating at least one of search results and advertisements for the user device based on the event data in the fragment records that remain associated with the chain ID.

Abstract: A method of authentication of an object between a monitoring station and a verification post in which the object to be monitored bears a first visible information element and a second information element in the form of an electronic tag. During the monitoring, the first and the second information element carried by the object are read with the aid of an appropriate reader and transmitted to a verification post by transmission elements. On receipt of this information, the verification post applies a rule of concordance to the elements transmitted and verifies that the information received does indeed correspond to an original object. If such is the case, the verification post dispatches a positive signal to the monitoring station; in the converse case, a negative signal indicating that the article is not an original article is sent.

Abstract: An adjustable microphone. The microphone includes a MEMS microphone, a charge pump, a preamplifier, a first analog-to-digital converter, a root mean square (RMS) power detector, and a logic circuit. The MEMS microphone is configured to provide a signal indicative of sound detected by the MEMS microphone. The charge pump provides a bias voltage to the MEMS microphone. The preamplifier receives the signal from the MEMS microphone, and outputs an amplified signal indicative of sound detected by the MEMS microphone. The first analog-to-digital converter receives the amplified signal and converts the amplified signal to a digital signal. The root mean square power detector is configured to detect a power level of the amplified signal and output an indication of the power of the amplified signal. The logic circuit receives the RMS power detector output and a control input, and adjusts the operation of the microphone based on the control input.
