Abstract: In embodiments, an apparatus for computing may include a receiver; a speaker; circuitry coupled to the receiver and speaker; and a service to be operated by the circuitry to receive an instance of a message via the receiver, and to conditionally affect a provision, through the speaker, an audio notification alert of the receipt of the instance of the message. In embodiments, to conditionally affect the provision may include to bypass or cause to bypass of the provision of the audio notification alert, on determination that another audio notification alert has been or will be provided by another proximally located apparatus for receiving another instance of the same message. Other embodiments may be described and claimed.

Abstract: Herein is disclosed a slack distribution system comprising one or more sensors, configured to deliver sensor data to one or more processors in a first vehicle; a wireless communication circuit, configured to wirelessly transmit to a second vehicle; one or more processors, configured to determine from at least the sensor data, during first vehicle deceleration, a slack distance between the first vehicle and the second vehicle; and when the slack distance is less than a predetermined threshold, to cause the wireless communication circuit to transmit to the second vehicle a slack request message, wherein the slack request message is a request to change the slack distance.

Abstract: Methods and apparatus for detecting breathing patterns are disclosed herein. An example wearable device includes a frame to be worn by a user in an environment. The example wearable device includes a first microphone carried by the frame. The first microphone is to collect breathing sound data from the user. An example wearable device includes a second microphone carried by the frame. The second microphone is to collect noise data from the environment. The example wearable device includes at least one processor to modify the breathing sound data based on the environmental noise data to generate modified breathing sound data and identify a breathing pattern based on the modified breathing sound data.

Abstract: A satellite communications system includes an orbiting communications satellite for relaying communications to and from a plurality of ground stations, and a network management center for making connections via the satellite between the ground stations in response to connection requests received via the satellite from the ground stations, the network management center being configured to provide both open-end service and closed-end service. The network management center of one embodiment is configured to provides both types of service according to a predefined channel access protocol that enables the ground stations to request the type of service desired. The channel access protocol may be configured to adaptively allocate channels to open-end service and closed-end service according to changes in the traffic pattern and include a free-access tree algorithm that coordinates collision resolution among the ground stations.

Abstract: A variable-delay, sine-cosine non-coherent demodulator recovers digital data angle-modulated upon a radio-frequency (RF) carrier signal, by frequency conversion of the carrier signal to a selected IF frequency, which is ideally equal to one-fourth of a sample frequency supplied to the demodulator. The IF signal is sampled at the sample frequency, and the samples are then sorted to provide a pair of baseband quadrature-phased I and Q signals. Each of the I and Q signals is delayed by a variable first delay T.sub.1 to provide first-delayed in-phase I.sub.1 and first-delayed quadrature-phased Q.sub.1 signals. These signals are then delayed by a second delay T.sub.2 to provide twice-delayed in-phase I.sub.2 and twice-delay quadrature-phase Q.sub.2 signals. The sum of the two delays is a constant related to the sample frequency, which itself is related to the data bit rate, but the first delay T.sub.1 is variably dependent upon the frequency offset between the IF signal and the sample signal.
