Generally, embodiments of a pre-chamber unit having a pre-combustion chamber including one or more induction ports in a configuration which achieves flow fields and flow field forces inside the pre-combustion chamber which act to direct flame growth away quenching surface of the pre-combustion chamber.

A pressure exchanger for transferring pressure energy from a relatively high-pressure fluid stream to another relatively low-pressure fluid stream is provided. A ducted rotor is positioned on a central axle between two end covers inside a pressure vessel with a coaxial inlet and outlet pair that is in communication with a pair of low pressure ports having inclination forming an inlet tangential velocity vector in the direction of rotor rotation and an outlet tangential velocity vector in opposite direction imparting a rotational momentum on rotor. A pair of high-pressure ports is adapted for flow without inclination and imparts no momentum to rotor and flow can be varied without impacting the rotor's RPM. The end covers have a sloped surface following a flat sealing area that increases the clearance in the direction of rotation causing increased outflow during depressurization and lower duct pressure before duct is exposed to low pressure port and furthermore causing increased inflow during the pressurization phase before duct is exposed to the high pressure port, which will dissipate pressure energy as opposed to producing cavitation or pressure waves with result wear and noise.

A bicycle configurable for operating using a speed based control system and scheme or a torque based control system and scheme. A speed sensor or a torque sensor may detect an operating characteristic of the bicycle and a controller may determine whether to operate using a speed based control system and scheme or a torque based control system and scheme based on the operating characteristic. A signal from a speed sensor or a torque sensor may be used for determining the mechanical limits of a CVT range and when to incorporate an electric motor.

A beat detection device includes: a pulse wave sensor adapted to detect and output a pulse wave signal; a body motion sensor adapted to detect and output a body motion signal due to a body motion of a human body; a pulse wave signal filtering section adapted to generate an adaptive filter based on the body motion signal to extract a noise signal in the pulse wave signal, and to output a beat signal obtained by eliminating the noise signal from the pulse wave signal; and a filter coefficient setting section adapted to set a coefficient of the adaptive filter to be a predetermined value in response to detection of increase in a body motion change beyond a predetermined threshold value based on the body motion signal.

A diffuser arrangement is provided in which a wall surface of the diffuser arrangement incorporates an upstream part and a downstream part with an aperture between them. There is a step displacement between the upstream part and the downstream part along with specific shaping of the leading edge of the aperture whereby fluid air flow is drawn into the aperture from a fluid flow whilst avoiding undue disturbance to that flow. The present diffuser arrangement allows incorporation within an engine without complex fabrication or structural requirements.

A method for controlling game play for use in a video game, wherein a plurality of possible animated actions can be taken by a game character in response to an input from a user provided through a game controller. The method includes: detecting user input from the game controller requesting an animated action by the player; reading an adrenaline value from a control element on the controller indicating a level of aggression desired by the user for the animated action; selecting an animated action from the plurality of possible animated actions based at least in part on the adrenaline value; and performing the selected animated action.

A hot gas deployment device for safely deploying a “hot” tear-gas canister to flush out barricaded law-resisters. The device includes an internal chamber for inserting the tear-gas canister therein, securing means to secure the canister in place during deployment, and a handle for easy operation. The chamber safely contains the hot-gases produced by the tear-gas canister to reduce the risk of causing a fire in the barricaded space. Tear-gas release orifices on the chamber's housing release the tear-gas from the chamber. One embodiment of the device includes a hollow spear for releasing the tear-gas through walls and other obstructions. Another embodiment of the device is suitable for hurling with a tear-gas grenade launcher.

An electrode for a plasma arc cutting torch which minimizes the deposition of high emissivity material on the nozzle, reduces electrode wear, and improves cut quality. The electrode has a body having a first end, a second end in a spaced relationship relative to the first end, and an outer surface extending from the first end to the second end. The body has an end face disposed at the second end. The electrode also includes at least one passage extending from a first opening in the body to a second opening in the end face.

A thermodynamic machine, comprising: a rotor, configured to rotate about a rotor axis, a working fluid circulation path and a coolant fluid path formed within the rotor, the coolant fluid path fluidically isolated from the working fluid circulation path, the working fluid circulation path spanning radially from the rotor axis to close to the periphery of the rotor; a working fluid circulation drive configured to drive the circulation of a working fluid about the working fluid circulation path; at least one working fluid cooler heat exchanger formed as part of the working fluid circulation path and the coolant fluid path, in use coolant fluid passing through the working fluid cooler heat exchanger to transfer heat from the working fluid to the coolant fluid, and; a working fluid heater in the working fluid circulation path configured to heat a working fluid circulating around the working fluid circulation path.

A portable, user shoulder supported spreader/blower unit includes an ergonomically configured housing which includes a section defining a storage bin for holding a quantity of salt or like chemical particulate material for spreading onto ground surfaces to prevent icing thereon in winter. A centrifugal distributor disk is located in a housing space section below the bin and, a bin discharge aperture aligns over a peripheral area of the distributor disk. A user controllable closure member selectively alters bin discharge aperture size and, hence, outflow quantity from the bin onto the distributor disk, the distributor disk rotating at high speed propelling particulate material out of the housing through a discharge nozzle thereon at a high speed. e.g., 60 m/sec when the unit is user in a spreader mode. To further enhance carry of the particulate material from the housing, a fan impeller mounted in the housing in the common space wherein the distributor disk operates, is rotated at high speed to produce air flow supplementing energy imparted to the particulate material. When the unit is used in a blower mode such as in a leaf collection operation, high pressure air from an outside source can be introduced into the unit so the airstream discharge from the unit is optimized to that required for leaf blowing.
