    Abstract: Various embodiments of a low-power-consumption analog-to-digital converter (“ADC”) for a touchscreen or touch panel in a capacitive sensing system are disclosed. The ADC is configured to operate in a first mode or a second mode. The first mode is characterized by a first resolution having a first number of ADC bits and a first level of power consumption associated therewith. The second mode is characterized by a second resolution having a second number of bits and a second level of power consumption associated therewith. The ADC operates under control of the controller and is configured such that the first number of bits is greater than the second number of bits and the first power level is greater than the second power level. The controller causes the ADC to switch from operating in the first mode to operating in the second mode when low radio frequency (RF) noise conditions are detected by sense circuitry, the ADC and/or the controller.

    Abstract: A sample feeding device for a trace detector is disclosed. The sample feeding device comprises: a sample feeding chamber disposed in the sample feeding device to desorb a sample from a sample feeding member; and a valve assembly configured to fluidly communicate the sample feeding chamber with a drift tube of the trace detector during feeding sample. With the above configuration of the present invention, for example, the sensitivity of the detector can be increased by improving the permeation ratio of the sample. In addition, interior environment of the drift tube is isolated from exterior environment to avoid a drift region of the drift tube from being polluted. The important parameters, such as sensitivity, a position of a peak of a substance, a resolution, of the detector can be kept constant. As a result, operation reliability and consistency of the detector can be achieved.

    Abstract: Various methods are described for using a local trust level and/or a general trust level to control access of data in PSN. Any PSN user can select other users with at least a minimum level of local and/or general trust for secure communications. The users with a trust level below a minimum trust level cannot access the data sent from him/her. The general trust level is controlled by access keys that are generated and issued by a trusted server. The local trust level controlled access keys are generated by each PSN device. Each PSN device issues the corresponding personalized secret keys to those users that satisfy the decryption conditions related to local trust level evaluated by PSN user itself. Both sets of keys can be applied at the same time to secure communication data in PSN controlled by both the general trust level and the local trust level.
