The length of a normal menstrual cycle is 28 days, plus/minus 7 days. That is, a period may occur 7 days before the expected date of the period or may be normally delayed for 7 days beyond the expected date. But, if the delay is more than 35 (28+7) days, then the cause of the delay needs to be investigated.

A proximity measuring apparatus (70) comprises an interrogator (80) for generating an interrogation signal encoded with a reference signature code comprising concatenated codes and emitting it as interrogating radiation. It also incorporates a transponder (90) for receiving the interrogating radiation, demodulating it to extract its signature code and then remodulating it after a delay period to provide a signal for reemission as return radiation therefrom. The interrogator (80) receives return radiation at its antenna (260) and demodulates it to extract its signature code and then correlates the code with the reference code to determine mutual correlation thereof. The interrogator (80) incorporates a computer (290) for controlling a scan direction of the antenna (260) and for measuring time delay between emission of the interrogating radiation therefrom and receipt of corresponding return radiation. The computer (290) computes distance and relative bearing of a transponder (90) providing the return radiation from the scan direction and the time delay. The apparatus (70) may be used for improving road vehicle safety.

The present invention relates to nanofibers that produce therapeutic amounts of nitric oxide after a delay period, which allows time to install or implant the device into a patient. The nitric oxide release is thus localized to the area of the organism where NO dosing is indicated. The delay time is achieved by cospinning the NO-producing fiber with a fiber that tends to sequester the former's NO-producing functional groups. Fibers of the present invention may be incorporated into medical devices such as stents or other implantable medical devices to prevent the formation of adhesions or scarring in the area of the implant.

In one illustrative example, a plurality of page message requests for a plurality of mobile devices which operate in a wireless communication network are received. One or more paging slots assigned to the mobile devices are identified for transmitting a plurality of page messages in response to these requests. However, the wireless network refrains from causing a page message for the mobile device associated with a tolerable delay indication to be transmitted within the one or more paging slots when a paging capacity limit of the one or more paging slots is reached. This allows higher priority page messages to be transmitted within the one or more paging slots. The wireless network subsequently causes a page message for the mobile device having the tolerable delay indication to be transmitted within one or more subsequent paging slots within a tolerable delay period corresponding to the tolerable delay indication. The mobile device may transmit the tolerable delay indication to the wireless network in response to identifying a predetermined condition, for example, identifying use of a high capacity power source.

Disclosed are systems and techniques by which a caller may specify a callee's telephone number and be connected directly to a carrier provided voice mail facility associated with the identified the telephone number, even though the callee's carrier may not be the same as the caller's carrier. In the disclosed technique, a telephony server places a “Send a call” request to a server which then sends a signaling call that busies out the channel associated with the callee. The telephony server places a second call (the actual voice message) upon confirmation that the signaling call has been initiated, forcing the second call to the carrier's voice mail facility associated with the callee, since the first signaling call busied the first channel. Prior to sending the signaling call, a database look up is performed to determine which carrier services the callee number. Once the carrier is determined, another memory look up is performed to determine the time delay associated with that carrier. The time delay is then counted upon initiation of the first signaling call and the signaling call terminated upon expiration of the delay period. A user interface is provided by which a caller may specify the number of the intended callee by either a web interface, an external telephony interface such as an Interactive Voice Response (IVR) facility, an interface mechanism internal to a caller's private telephony network, or an automated number capture mechanism.

InactiveUS7061215B2Simple and low-cost deviceApparatus with intermediate ac conversionDc source parallel operationSwitching frequencyAnalog signal
A cascadable power regulator including a programmable delay unit and PWM control logic. The programmable delay unit initiates a delay period in response to a digital input signal and asserts a digital output signal upon expiration of the delay period. The PWM control logic controls a PWM cycle in response to the digital input signal and in response to an output control condition. The cascadable regulator uses digital signals to communicate between channels. Digital signals are not prone to the same kind of signal degradation or noise susceptibility as analog signals. Thus, the number of phases is not limited, the physical separation between the regulators is not limited, and the switching frequency is not as limited. There is no clock signal from a separate controller so that the controller is a relatively simple, low-cost device. Since there is no clock, a unique self-oscillating system is achieved using the cascadable regulator.
