    摘要： A control system is provided for use in a power tool. The control system includes: a rotational rate sensor having a resonating mass and a controller electrically connected to the rotational rate sensor. The rotational rate sensor detects lateral displacement of the resonating mass and generates a signal indicative of the detected lateral displacement, such that the lateral displacement is directly proportional to a rotational speed at which the power tool rotates about an axis of the rotary shaft. Based on the generated signal, the controller initiates a protective operation to avoid further undesirable rotation of the power tool. The control scheme employed by the power tool may initiate different protective operations for different tool conditions.

    摘要： A clutch arrangement for a power tool having a multi-speed transmission. The clutch arrangement includes a clutch member and a follower member. The clutch member is coupled to a member of the transmission that is proximate the torsional input of the transmission and which must be in a non-rotating position to permit the transmission to perform a torque multiplication operation. The follower member is biased into engagement with the clutch member to inhibit relative rotation therebetween. As the clutch member and the transmission member are coupled to one another, the transmission is able to perform a torque multiplication operation. When, however, the torsion that is exerted onto the clutch member is sufficient to overcome the frictional engagement between the follower and clutch members, the clutch member, and the transmission member, rotate, thereby inhibiting the capability of the transmission to continue to perform the torque multiplication operation.

    摘要： The invention relates to the field of strand displacement, and provides a color image encryption method based on a DNA strand displacement analog circuit. Firstly, a reaction module with a light-emitting group and a quenching group is designed through Visual DSD software, and by utilizing the equivalence of a DNA strand displacement reaction module and an ideal reaction module, an analog circuit formed by the DNA strand displacement reaction module can perform analog on the dynamics characteristics of an ideal reaction network formed by the ideal reaction module, wherein the Rössler chaotic system can be described by the idealized reaction network. Secondly, data generated by the DNA strand displacement analog circuit is converted into a chaotic sequence matched with a plaintext image in size after being extended, and finally, the color image encryption effect is achieved through scrambling and diffusion operations.

    摘要： This invention discloses a high strength security lock cylinder. The lock cylinder includes a front lock housing, a front lock plug, a rear lock housing, a rear lock plug, a horizontal bar, and a lock cam. The front and rear lock plugs are connected with the lock cam and can drive the lock cam to rotate. An electronic locking mechanism is placed inside the front lock plug. The rear lock plug is connected with an axel, which is connected with a knob that contains a digital control board and an electrical power source. A signal transmission channel is formed along the horizontal bar for transmitting signals between the electronic locking mechanism and the digital control board. The lock cylinder is flexible, strong, and resistant to drilling and lock picking and it can be digitally controlled. This reduces the security risks caused by misplacement or unauthorized use of keys.

    摘要： A network environment includes a wireless access point providing access to a corresponding network. A server resource initiates verification (such as authorization) of a mobile communication device attempting to establish a secured wireless link between the mobile communication device and a network access point. Based on an outcome of the verification, the server resource produces control information. The server resource forwards the control information to a gateway resource that controls a flow of communications between the network access point and a network. The gateway resource facilitates transmission of one or more messages to the mobile communication device in accordance with the control information.
