30results about How to "Prevent unwanted changes" patented technology

A laser-based method and system for processing targeted surface material and article produced thereby are provided. The system processes the targeted surface material within a region of a workpiece while avoiding undesirable changes to adjacent non-targeted material. The system includes a primary laser subsystem including a primary laser source for generating a pulsed laser output including at least one pulse having a wavelength and a pulse width less than 1 ns. A delivery subsystem irradiates the targeted surface material of the workpiece with the pulsed laser output including the at least one pulse to texture the targeted surface material. The pulsed laser output has sufficient total fluence to initiate ablation within at least a portion of the targeted surface material and the pulse width is short enough such that the region and the non-targeted material surrounding the material are substantially free of slag.

The mobile application security system and method in accordance with the invention increases the overall level of security in using a mobile application. In a preferred embodiment, the system may use a peer-to-peer architecture wherein each host of a mobile application is a node of the peer-to-peer network. In operation, when a mobile application jumps between hosts (nodes), information about the mobile application is generated and sent to a central security enforcement node so that the central security enforcement node may perform various security checks. The security checks ensure that the security of the mobile application is not compromised.

A method and system is described to improve the reproduction of sound of an acoustic musical instrument. According to one embodiment, a first microphone is placed at a proximate location to the musical instrument to pick up the sound of the musical instrument. The sound as picked up by the first microphone is compared to a reference sound of the instrument (e.g., the sound of the instrument as perceived at a normal listening position). Based on this comparison, a tailor-made equalizer is designed to compensate for the differences between the sounds as picked up by the first microphone and the reference sounds of the musical instrument. Accordingly, using the tailor-made equalizer allows the reproduction of sound from the first microphone to have a quality similar to that of the reference sound of the musical instrument. In an implementation of the above system, a filter arrangement is provided having a low-pass and a high-pass filter that allows separate control of the frequency and / or gain for each filter.

The invention provides an adjustable automobile pedal which comprises an upper arm, a lower arm and an adjusting bolt. A pedal body is installed at one end of the lower arm. A first rod and a second rod extend from the upper arm in the lateral direction of the upper arm. A threaded hole is formed between the first rod and the second rod in the length direction of the upper arm. A first unthreaded hole, a second unthreaded hole and a third unthreaded hole are sequentially formed in the lower arm in the length direction of the lower arm. The first rod and the second rod are sleeved with springs. The first rod and the first unthreaded hole are in clearance fit, the second rod and the third unthreaded hole are in clearance fit, and the springs are clamped between the upper arm and the lower arm. The adjusting bolt penetrates the second unthreaded hole and then is in thread fit with the threaded hole. The adjusting bolt can rotate in the second unthreaded hole and meanwhile drive the lower arm to move in the axial direction of the adjusting bolt. The invention further provides an automobile. By the adoption of the adjustable automobile pedal and the automobile, driving comfort and safety can be improved.

A first stud and a second stud extend from the upper arm in the lateral direction of the upper arm. A first unthreaded hole, a second unthreaded hole and a third unthreaded hole are sequentially from in the lower arm in the length direction of the lower arm. The first stud penetrates through the first unthreaded hole and then is in threaded fit with a first gear. The second stud penetrates through the third unthreaded hole and then is in threaded fit with a second gear. Springs are clamped between the upper arm and the lower arm. A third gear is fixed to the adjusting shaft. The adjusting shaft is in running fit with the second unthreaded hole, and the third gear is engaged with the first gear and the second gear at the same time. The third gear rotates so as to drive the first gear and the second gear to synchronously rotate outwards and rightwards or rotate inwards and leftwards. The invention further provides an automobile. By means of the adjustable automobile pedal and the automobile, the driving comfort and safety can be improved.
