  • Publication number: 20130004811
    Abstract: A battery temperature sensor may include a substrate and a thin film resistive temperature device (RTD). The substrate can be layered on a battery cell element. The battery cell element can be an anode, a cathode, and a separator between the anode and cathode used in a battery cell. The thin film resistive temperature device (RTD) on the flexible substrate can change resistance with a change in temperature. A battery cell housing can enclose the thin film RTD.

  • Patent number: 8180028
    Abstract: Disclosed are systems and methods which allow a calling party to store messages for a called party even if the called party does not already have message storage facilities, provided the calling party and/or called party meet certain parameters. Delivery of the message is controlled by the called party and may require the called party to agree to pay for the message delivery service. In a further embodiment, a call processing system is operable to screen outgoing calls from various callers according to a first set of criteria and if a call is not completed to a called party a second set of criteria is used to determine if a message can be stored awaiting retrieval by the called party. If desired, a return message from a called party to a calling party can be stored.

  • Patent number: 7860226
    Abstract: Disclosed are systems and methods which provide techniques providing account setup, management and transaction authorization determinations in real-time using transaction interrupt messaging. Embodiments preferably take into consideration the quality of one or more parties to the transaction and the means by which charges may be rendered to them when making account setup, management, and/or transaction authorization determinations. Accordingly, transactions, such as collect calls, meeting at least some minimal risk threshold may be completed on a first call attempt, even where a pre-arranged billing agreement or other business relationship is not previously in place.

  • Patent number: 7519169
    Abstract: Systems and methods for the dissemination of information from a controlled environment facility employ facility information management functionality managing resident information and facility information, and call manager functionality selectively providing at least a portion of the resident information and/or the facility information to an outside party in an automated manner. The invention may employ outgoing IVR functionality to provide select portions of the resident information in response to the call manager recognizing that a call is a first call by a resident, or a first call to a particular telephone number by a resident. The invention may manage information related to providers of services or goods for residents of a facility, provide an outside party this information, and notify a selected provider of selection of that provider by the outside party to provide goods or services for a resident.
