Abstract: A system and method for performing range of motion measurements in an unsupervised manner. A user equipment with one or more cameras may be used with an application on the UE using the one or more cameras to measure range of motion of a user of the UE. The patient may record movement of the part of the body of interest, such as the head. The movement may be recorded in three dimensions (e.g., calculated from two dimensional coordinates of an image) and processed by the application, and the three rotational angles calculated corresponding to the difference between the final position of the head and the initial position of the head at the beginning of the recording. As a result, facial recognition is used to improve monitoring of range of motion during surgical recovery in an unsupervised environment.

Abstract: Systems, methods, and devices for determining a length of a connecting rod are described. In some aspects, a method includes obtaining at least one radiographic image representative of a first medical device inserted into a body of a patient, and determining a calibration factor of the at least one radiographic image. The method may further include receiving one or more rod length selection parameters, and determining, based on the at least one radiographic image, a first rod connection point and a second rod connection point. The method may further include determining, based on the first rod connection point, the second rod connection point, and the one or more rod selection parameters, a length of the connecting rod. The method may further include outputting the length of the rod to a display.

Abstract: Systems and methods for user-guided iterative node discovery and topology discovery in a network of nodes involved in secure and reliable data transfer.

Abstract: A particle detection system uses a reflective optic comprising a curved surface to detect high angle scattered light generated by a particle in a liquid medium, when a laser beam is incident on the particle. When the particles transit the laser beam, light is scattered in all directions and is described by MIE scattering theory for particles about the size of the wavelength of light and larger or Rayleigh Scattering when the particles are smaller than the wavelength of light. By using the reflective optic, the scattered light can be detected over angles that are greater than normally obtainable.

Abstract: A material for use as a bearing sliding surface and a bearing having the material are described, the material comprises tin and having therein from 1 to 5 wt % of a metal selected from the group comprising nickel, cobalt and iron.

Abstract: A plain bearing comprises a strong backing, a layer of silver and an overlay coating of a metal containing diamond particles. The diamond-containing metal may be of silver, lead, lead/tin, lead/indium or lead/tin/copper. The diamond may be natural or synthetic.

Abstract: Thin-walled bearings (10) each including a layer (16) of an aluminium based, or copper based, bearing material bonded to a steel shell, has an overlay (20) of one or more of the elements lead, tin, indium, copper, nickel, zinc and antimony. A flash (24) less than two micrometers thick and of one or more of the elements iron, chromium, nickel, cobalt, gold, silver and copper, is provided in any convenient way on the initially unmodified exposed surface portion of the overlay. The flash (24) is caused to react with the, or at least one constituent, element of the overlay (20) to modify the surface portion (22) of the overlay to become hard and wear-resistant. The material of the flash (24) forms at least one intermetallic compound, and/or solid solution, with the material of the surface portion (22) of the overlay (20). The bearing may be heated to a temperature at which the flash (24) reacts with the overlay (20) to form the required intermetallic compound, and/or solid solution, at a desired rate.

Abstract: A method of packing garments for transportation or storage in which each garment is enclosed unfolded inside its own garment cover, the garment cover commensurate in size with the garment and the garment cover formed from a low-friction fabric material. The garment covers are packed adjacent one another in luggage, thereby reducing friction between the garments so that fewer wrinkles in the garments occur when they are transported or stored.
