Abstract: A device for the measurement of forces on the tip of a jet injector drug ampoule. Sensor consists of multiple spokes with strain sensing capability where each spoke has a modified linkage to allow for quasi-free bending behavior on one spoke end. By using the strain output of all three full bridges in parallel, it is possible to discriminate between lateral forces and axial forces directed collinear with the center axis of the ampoule applied to the tip of the nozzle. This information can be relayed to the user to attain, for example, a pre-determined contact force between the nozzle and an area receiving an injection.

Abstract: A device for the measurement of electrical properties on a surface. Sensor consists of several conductive elements arranged at vertices of a three-dimensional geometry. As such, the device achieves a favorable sensing configuration regardless of initial orientation. The device includes circuitry for interfacing with the conductive elements. This circuitry determines the electrical properties of the surface. The measurement has many uses, one of which is to discriminate between dry and wet surfaces. This patent presents various analysis methods to determine the electrical property.

Abstract: A system includes a device (100) for imaging a skin abnormality of a patient, and a web interface (115, 125). The imaging device has a camera (103) recording a plurality of images from locations separated by that distance, thereby obtaining a stereoscopic image of the skin abnormality. The imaging device may be configured as a handheld unit, with the camera a plug-and-play webcam and the device having a USB connection (114) to a computer (110, 120). The web interface (115, 125) links the computer (110, 120) to a web site providing access to storage of the image data. The web interface provides a patient portal for entering information regarding the skin abnormality, and a doctor portal for accessing patient medical history and entering clinical data regarding the skin abnormality. The system may further include a server (160) to receive and analyze the image data, generate 3D stereoscopic images of the skin abnormality, and compute metrics for clinical evaluation of the skin abnormality.
