Abstract: A dynamic compressor includes an impeller having impeller vanes disposed around a hub, a shroud, and a diffuser having a shroud surface adjacent to the shroud and a hub surface adjacent to the hub, wherein the diffuser is circumferentially disposed around the impeller. The diffuser includes a plurality of diffuser vanes extending from the hub surface to the shroud surface, each having a vane leading edge and a vane trailing edge. The diffuser includes a centrifugal acceleration stabilizer ring formed in the shroud surface located in a vaneless region defined between an impeller trailing edge and the vane leading edge. The centrifugal acceleration stabilizer ring stabilizes the flow of the fluid by changing the circumferentially-flowing high velocity fluid flow exiting the impeller into a radially-flowing high velocity fluid flow before entering the diffuser, improving the efficiency of the dynamic compressor.

Abstract: An appliance includes a system on chip (SOC) and converter. The appliance accepts A/V data (e.g., HDMI®, SDI®, IP) from external sources, encodes A/V data using an encoder of the SOC and performs additional services via other computational components of the SOC. The SOC may be a mobile SOC. The appliance may operate as an edge appliance, edge encoder, or edge-based origin-server, for instance at an edge endpoint of a mesh network, allowing many-to-many distribution of A/V data, performing computationally efficient A/V encoding, while also making available additional computational resources (e.g., cycles of CPUs, GPUs, DSPs, AI/ML NPUs) to provide other services at the edge in addition to efficient A/V encoding.

Abstract: A system, in certain embodiments, includes a centrifugal compressor diffuser vane including a leading edge, a trailing edge, and a constant thickness section extending between the leading edge and the trailing edge. A radius of curvature of the leading edge and a radius of curvature of the trailing edge vary along a span of the vane. A ratio of a length of the constant thickness section to a chord length of the vane is at least approximately 50%, and the ratio is substantially constant along the span of the vane.

Abstract: A modular emergency stop device including a switch unit and a control unit. The switch unit includes a switch which converts from a normal state to an emergency state when an emergency stop is necessary and a housing for the switch. The control unit includes a controller which controls a power source for a machine and a housing for the controller. The switch unit's housing and the control unit's housing are adapted to be selectively coupled together and uncoupled from each other. The switch is operably coupled to the controller when the housings are coupled together whereby the controller may appropriately control the machine's power source when the switch is converted to the emergency state. To replace the switch, the switch's housing is uncoupled from the controller's housing to remove the switch unit and a new switch unit is coupled to the controller's housing.

Abstract: An in-line data protector for preventing a test set from accessing a telephone line under a predetermined condition is disclosed. The in-line data protector selectively connects the test set and the telephone line responsive to detection of a data signal on the telephone line. The in-line data protector includes a power circuit for providing general operating power, a processor connected to the telephone line, and a relay serially connected between the telephone line and the test set. When general operating power is received, the processor analyzes the telephone line by emulating a single band filter. By using a single band filter, a very good determination can be made as to whether a signal on the telephone line is a data signal or a voice signal. If the signal is not a data signal, the processor instructs the relay to close, thereby connecting the telephone line to the test set.

Abstract: The present invention solves both the dangling pointer problem and the garbage collection problem in software systems. Safe object pointers are divided into strong and weak pointers. Strong pointers point to an object unless they are explicitly assigned a new value, set to null, or destroyed. Weak pointers point to an object as long as the object has not been destroyed. If an object is destroyed, the weak pointer effectively becomes null, thus allowing the breaking up of cycles of references in a computer memory.

Abstract: A cutter tool cleaning assembly comprises a pair of peripherally opposed wire brush wheels mounted on a metal cutting broach machine so that the machine cutter bar engages and passes between the wheels to cause rolling contact of the wheels with the cutter bar to dislodge metal chips.
