A device for providing an indication of moisture present in skin of a user includes a device body including a skin contact portion. A sensor circuit is located in the device body. The sensor circuit is configured to produce an output signal having a signal value that corresponds to moisture level in the skin with the skin contact portion in contact with the skin at a skin measurement location. A controller is in communication with the sensor circuit and is configured to determine the signal value of the output signal. The controller stores a first signal value in memory corresponding to a first output signal produced with the skin contact portion in contact with the skin of the user at a first skin measurement location. The controller stores a second signal value in memory corresponding to a second output signal generated with the contact portion in contact with the skin of the user at a second skin measurement location different from the first skin measurement location. The first and second signal values are used to indicate moisture present in the skin of the user at the second skin measurement location.

A vibrator coil (10) is applied to the skull (30) by adaptation of a commercially available transcranial Doppler monitoring harness (40) during MR applies mechanical waves in the acoustic waves through the skull to the brain. Utilizing magnetic resonance elastography (MRE), non-invasive estimation of tissue elastic properties in three dimensions occurs. The propagation of the acoustic waves through brain tissue, coupled to phase alteration of voxel isochromats in the presence of applies motion encoding magnetic field gradients allows measurements of brain elasticity.

An animal-resistant system for inhibiting access to refuse containers by animals is disclosed. The system comprises at least one latch mechanism, at least one actuation member, at least one shroud member, and a cover defining an opening which permits access to the actuation member. The actuation member communicates with the latch mechanism so as to move the latch mechanism between the latched and unlatched positions. In the latched position, the latch mechanism secures the container lid to the container base, substantially inhibiting access to the container. The access hole and actuation member are dimensioned and positioned on the container in a selected manner so as allow human hands access to the actuation member and unlatch the container while simultaneously inhibiting such access by animals. The shrouds are further configured to inhibit forcible entry into the container when the system is latched.
摘要:
The apparatus of one embodiment of the present invention is comprised of a flexible sheath instrument, a flexible guide instrument, and a tool. The flexible sheath instrument comprises a first instrument base removably coupleable to an instrument driver and defines a sheath instrument working lumen. The flexible guide instrument comprises a second instrument base removably coupleable to the instrument driver and is threaded through the sheath instrument working lumen. The guide instrument also defines a guide instrument working lumen. The tool is threaded through the guide instrument working lumen. For this embodiment of the apparatus, the sheath instrument and guide instrument are independently controllable relative to each other.

A collapsible cart and tree stand operable in cart, tree stand and collapsed configurations is disclosed. The cart includes a substantially planar deck, wheels removably and rotatably mountable to the deck, and a handle removably connectable at a front edge of the deck. In variations, the cart can hitch to a vehicle, hitch to a bicycle, contain loads in a bin, and includes side rails and a backrest for carrying an injured person. In the collapsed configuration, the handle and wheels are removably stowable adjacent to said deck, with two wheels in substantially coplanar relation to each other. In the tree stand configuration, the deck has a rear edge whose left and right extremities are rearward of an intermediate portion therebetween which is adapted to engage the surface of a tree. A tree support for supporting the deck is provided which is removably attachable to a tree.
摘要:
A methods using a robotic catheter system to perform a procedure on a patient includes generating a control signal corresponding to movement of a master input device, and moving a plurality of drive elements of an instrument driver in response to the control signal, the drive elements operatively coupled to a corresponding plurality of control elements of an elongate guide instrument, the control elements secured to a distal end of the guide instrument and moveable axially relative to the guide instrument such that movement of the drive elements causes a corresponding movement of the guide instrument distal end.
