Abstract: A customer self-service tuning system assists a mobile device user in adjusting his network settings and device configuration. Device, network and performance metrics are stored for a population. Over time all of these suggest changes in the device or network that change measured performance. The potential improvement(s) are presented to the user for selection. Performance measurements are taken and the user can choose to go forward with the new configuration or to revert. Each time a user requests self-care service, a new cohort is extracted from the then current overall population and analyzed for similarity to the user at that point in time. Each time an improvement is selected, the history of device states and network states is augmented. Identified variances are transformed into an action plan specific to a user and implemented on the device or network upon concurrence.

Abstract: A system communicatively couples a server to a plurality of mobile wireless device clients to receive and track customer care related information which has been captured on any one of the clients. The server uses information sent by a client to initiate a customer care request ticket and responds to the client request with a ticket number and request description compiled using the information from the client. A system receives from a mobile device user a request to tuneup, a devstate extracted from a cache stored in the mobile device, and proposes at least one delta devstate operation to resolve the perception; making an adjustment or guiding the user to make an adjustment to execute the proposed delta operation; and at the end of an evaluation period, offers to revert to the stored prior state; to accept the delta state; or to continue the tuneup process.

Abstract: A gas detector for detecting the presence of a light absorbing gas within an atmosphere (10) containing the gas includes a light source (12), a detector (14) arranged to detect a presence of incident radiation from the light source (12) and to provide an output signal (46) representative of the level of incident radiation from the light source (12). Electronic circuitry (130) is arranged to process the output signal (46) to provide an indication of the incident radiation. A power supply (40, 36) for cyclically energizing the light source (12) is also provided. The power supply is arranged to deliver substantially constant power at the or each level of energization of the light source (12).
