The present disclosure describes a device and methods for safely and accurately placing screws into bones with a powered driving device. By employing multiple layers of fail-safe features and image-guidance systems, the powered driving device provides safe, accurate, and efficient screw placement. That is, the powered driving device may continuously monitor a screw advancement and placement and may automatically shutdown when improper placement is detected. Monitoring placement may be conducted by a microcurrent-monitoring system, by an image-guidance system, or by any other appropriate sensory system. Additionally, upon detecting that screw insertion is complete, the powered driving device may be automatically shutdown. As screw placement is continuously simulated by image-guidance in real time, multiple redundant verification steps are eliminated, providing highly accurate screw placement while decreasing clinician error, device contamination, and surgical time, the decreased surgical time associated with decreased patient-recovery time and associated medical costs.

Methods and apparatus for connecting to a bone, which avoid the use of bone screws. A triangular shaped modular implant is used, with two sides of the structure and their respective vertex secured generally within the bone, with the base of the triangle outside the bone. These two arms, whether straight or arcuate, are cannulated, and are held together at their distal ends by a tightened cable that runs through both of the arms. The proximal ends of these arms are connected to a base side that completes the triangular structure. The device may be inserted into a vertebra and the base used for vertebral fusion. Alternatively, the arms themselves may be used to stabilize and fixate adjacent vertebrae, by insertion through adjacent vertebrae trans-segmentally. In the latter case, the vertex may be within the intervertebral space or within the vertebral body close to the intervertebral space.

The preferred embodiment of the invention is a multi-channel system that focuses the low mega Hertz ultrasound at user selectable depths, where fat cells are to be emulsified. The system has independent user control of the main emulsifying property, cavitation, and thermal heating, which can independently be used for skin tightening. One part of the system is a handheld transducer, in shape similar to a typical small diagnostic ultrasound transducer. The other part of the system includes a transmitter with internal tracking of procedure time and with a disabling feature.

A device constructed of a material strong enough to withstand the torque of a typical air wrench or cheater bar used by a lawn mower repair shop or a homeowner. One end of the device must have an opening and be of the size as to allow a lawn mower blade to be inserted inside of it. The portion containing the tip of the blade may include a leveler and / or retainer to raise the device to approximately the horizontal plane of the mower blade and the lower edge of the mower deck. The device includes a restriction leg to provide a prop against any protuberance on the side of a single-blade mower deck or on the side or within the deck on a multi-blade mower deck. To provide economics for manufacturing, one size should fit most blades and the device should require a limited quantity of materials and fabrication.

The invention relates to a method for monitoring the security of an area, a corresponding security monitor device and a wireless access device. The method comprises steps of: determining whether there is at least one first mobile device accessing a wireless access device that serves said area; starting to monitor a breach of security conditions, if there is no at least one first mobile device accessing the wireless access device; and, generating an alarm signal and sending said signal to one of said at least one first mobile device, if the breach of security conditions is detected.
