Abstract: Disclosed herein are system, method and apparatus with environmental noise cancellation. The instant disclosure is particularly adapted to a receiver module having at least two inputs. The two inputs respectively receive a main audio portion and the audio with majority of environmental noise. The system firstly calibrates the audio signals to reduce the error caused by the difference between the two inputs. An adaptive beamforming technology and a speech extractor are respectively used to extract the environmental noise portion with less main audio and the main audio portion with less noise. After a process of time-to-frequency domain transformation, a non-linear noise suppression technology is introduced into estimating the environmental noise and acquiring a gain. After noise suppression processed with the gain, a sequence of audio signals is output after a frequency-to-time domain transformation.

Abstract: A device for delivering a predetermined amount of torque to a tool. The device has a handle and a cam assembly located within the handle. The cam assembly has a cam member integrally formed with a drive shaft. An adjustment ring is capable of rotating the cam assembly to different positions related to different levels of torque. A plunger will be biased against an exterior surface of the cam member to provide the different levels of torque delivery.

Abstract: A ratchet screwdriver with an assembly of a handle (10), a body (17), a gear (56), a pawl (21, 22, 71), and a selector (27) movable on the assembly. The selector carries a pawl actuator (38, 81) for pivoting the pawl, and there is a rotation lock (42, 92) on the selector for releasably holding the rotated selector. The selector can be axially, and also rotationally, movable on the body for controlling the lock. The assembly is along an axis (A), and there are a member (44) and axial force appliers (62, 64) effective between the body and the member, thus restricting axial movement in the assembly. There is provision for assembly along the axis from adjacent the handle. There are modifications and an assembly method.

Abstract: A ratcheting assembly for a tool comprising a housing, a gear supported by a hollow shaft located in the housing and a pawl to engage the gear. A ring in contact with the housing allows adjustment of the ratcheting assembly. The assembly can the releasably lock the tool within the ratcheting assembly by way of a locking mechanism located within the shaft. The assembly further has a compressible collar that will be used to release the tool from the ratcheting assembly.

Abstract: A torque-limiting and ratcheting driver. The drive comprises a handle having an enclosed end and an open end, which houses a drive assembly. The drive assembly comprises a drive shaft, a drive clutch member and a camming clutch member supported by the drive shaft. The camming clutch member is coupled to the drive shaft, and the first drive clutch member and second camming clutch member are biased towards one another. The drive assembly has a locking screw supported by the drive shaft, with the locking means located at the enclosed end of the handle. The drive assembly is secured with the housing. The driver also comprises a ratcheting assembly connected to the handle, independently assembled of the drive assembly.

Abstract: A holder for replaceable tools and having a body with an opening along a longitudinal axis for snugly and individually receiving various tools. Two balls are on the body for engagement with the tools, and there is a projection into the opening for contacting the tool in a location diametrically opposite the location of the balls. A sleeve member is slideable on the body, and has two sets of camming ramps and cylindrical surfaces extending radially over the balls for controlling the radially location of the balls relative to the tool. The tool has a surface for abutting the body projection to thereby hold the tool free of radial deviation relative to the holder axis.

Abstract: A limiter torque wrench and method having a handle and a jaw pivotally connected together along an axis and for pivoting of the handle upon applying a quantifiable torque. A cam and spring-loaded follower are interconnected between the handle and the jaw. A ratchet is connected to the cam for return of the cam to a starting position and with minimal torque and after application of the limited torque. There is a second ratchet engagable with a workpiece and a pawl engages the second ratchet and a pusher engages the pawl offset from the axis for optimum engagement force on the engaged pawl.

Abstract: A torque-limiting driver. The driver comprises a handle having a housing, a drive assembly located the housing. The drive assembly comprises a drive, a drive clutch member supported by the drive shaft and secured to the housing, a camming clutch member supported by the drive shaft and interacting with and biased against the drive clutch member.

Abstract: This invention puts forward a process of preparing butyl rubber. High gravity devices are used as polymerization reactor. The mixture of isomonoolefin and conjugated diolefin monomers and the diluent, and the mixture of the initiator and diluent are pumped at a certain ratio into a high-gravity reactor to conduct cationic polymerization in the high-gravity environment. After polymerization, the monomers and the diluent are removed from the product to obtain butyl rubber polymers with number-average molecular weight of 80000˜300000 and molecular weight distribution index of 1.9˜3.6. The high gravity polymerization method of this invention can tremendously intensify micro-mixing, mass transfer and heat transfer in the reaction. Compared to the conventional stirred polymerization method, this invention features small reactor volume, at least 30-fold shorter residence time of substances in the high gravity reactor, low cost, low energy consumption and high production efficiency.
