Example techniques are provided for controlling volume of A/V devices using an improved volume control. The volume control may be implemented as a slider, where the sliding element is temporarily slid in response to user input (e.g., touched and dragged by the user), but then automatically “snaps” back to the center of the slider's range when the user input ends (e.g., is released by the user). Movement of the element from the center is interpreted as a relative volume adjustment, with the rate of volume change being proportional to the distance between the center of the range and the temporary position of the element. An indicator is provided indicating the rate, to provide user feedback. The volume control may be utilized as a master volume control in a home automation system.

An event tracking system tracks customer interactions to obtain product information that are made across plural contact mediums and displays an intuitive directed graph for analysis of the customer interactions. Each customer interaction is logged at each contact medium with a labeled reference associated with the content of the interaction, a time stamp and an identifier for the product or product user. An event modeling engine analyzes the log to identify contact sessions as contacts by the same identifier within a predetermined time so that an event tracking graphical user interface module prepares each contact session for display as a path of nodes interconnected by edges. Selected directed graph characteristics are highlighted, such as transitions from one contact medium to another or contact session volumes associated with an edge that have a relative volume compared with other contact sessions.

A needle assembly includes a transparent or translucent housing with a fluid inlet and outlet end, a flashback chamber, and a venting mechanism therebetween. The venting mechanism includes a blocking member to control the fluid flow in the venting mechanism so that it flows along the longest path through the vent. Substantially axially aligned inlet and outlet cannulas extend from the housing and communicate with the chamber. A sealable sleeve covers the external end of the outlet cannula. Relative volumes of the cannulas, the chamber, and the sleeve are selected to provide rapid reliable flashback indicative of venous entry with an internal vent positioned within the housing to divide the interior into first and second chambers, with the second chamber being adapted to maintain a negative pressure therein relative to the external environment so as to inhibit leakage of blood from the needle tip on withdrawal from the patient.

An audio mixer system is described for producing coded output in which at least a left audio signal, a right audio signal and a surround audio signal are encoded in two output channels so that the surround signal can be decoded from the difference of the two output channels. The system comprises means for generating position data designating a desired position for a sound source in a 360 degree sound field. Logic is provided for determining the relative volume of the sound source in the left, right and surround audio signals from the position data. A signed continuity factor is maintained so that the sign of the continuity factor is changed in response the desired position crossing a nominal position of the surround signal in the sound field and logic is provided for encoding the sound source data into the two output channels in accordance with the determined relative volume of the sound source in at least two of the left, right and surround signals each multiplied by the continuity factor. This reduces audible artifacts associated with phase discontinuities in the output signals either side of the surround speaker nominal position.

A cushion for a distal cup of a prosthetic socket has a total volume that includes a solid thermoplastic composition volume and a void volume. A ratio of the solid composition relative volume to the total volume yields a relative thermoplastic elastomer fill volume that is correlated with an elastic modulus of the cushion. The relative thermoplastic elastomer fill volume can vary regionally within the cushion in a customized manner, and accordingly, so can the elastic modulus and the durometer. Varying the elastic modulus or durometer regionally within a cushion, such as by 3D printing the cushion, provides therapeutic and prophylactic benefits in the application of the cushion to articles that interface with the body, such as a cushion disposed in the distal portion of a prosthetic socket for a residual limb of an amputee.
