Abstract: A monitoring system in a medical facility provides an identification device to a patient and a data acquisition device to a health-care worker. The identification device wirelessly emits a first signal that identifies the patient and the data acquisition device emits a second signal. A determination is made in response to the first signal and the second signal, whether the health-care worker is absent from being near the patient. For example, absence of the health-care worker is determined when a data reader receives only the first signal. This system detects when a patient requiring continuous observation is not in the presence of a health-care worker. In that case, an alarm message is sent to supervisory personnel.

Abstract: An electric machine is described herein. The machine includes an internal stator provided with a central opening. A generally cylindrical cooling assembly is mounted inside the central opening via a first key and keyway arrangement. The cylindrical cooling assembly is mounted to the casing of the electric machine via a second key and keyway arrangement.

Abstract: A shelving assembly including at least one shelf member and at least one upright frame member wherein the frame member includes at least vertically arranged couplers and the shelf member includes two other vertically arranged couplers on one lateral edge where the couplers on either the shelf member or frame member include pins and the couplers on the other of the shelf and frame member include slot delineators and where the slot delineators open in the same direction so that, with the pins received within the slot delineators, the shelf member can be detached from the frame member by moving the shelf member in directions perpendicular to pin axis.

Abstract: A method and apparatus for generating stator and rotor resistance estimate, the method including the steps of providing high frequency injection voltage signals to a three phase motor, rotating three phase feedback current therefrom, converting the feedback currents to two phase currents that represent the high frequency component of the current vector wherein the d and q axis components are within a two phase voltage coordinate system and driving a regulator via one of the current components to generate a lag angle estimate, the lag angle estimate used to solve any of several different equations to calculate the stator and rotor resistance estimates.

Abstract: A method and apparatus for reducing parasitic distortion in terminal voltages connected to a PWM inverter, the method comprising the steps of receiving each of a command operating frequency and a command carrier frequency, comparing the command operating frequency to low and high threshold operating frequency values, and where the command operating frequency is less than the low threshold frequency, restricting the carrier frequency to a minimum carrier frequency, where the command operating frequency is greater than the high threshold frequency, setting the carrier frequency equal to the command carrier frequency and, where the operating frequency is between the low and high threshold frequencies, setting the carrier frequency to an intermediate value between the minimum carrier frequency and the commanded carrier frequency.

Abstract: A common mode and differential mode inductance assembly including first and second torridial cores wherein first and second windings are wrapped about first and second segments of the first core and the first core forms a first surface and wherein the second core forms a second surface and is positioned adjacent the first core such that the first and second surfaces oppose each other and a gap is formed between the first and second surfaces.

Abstract: A method of supporting a breast in the correct position for breastfeeding by utilizing a support member that is placed against a mother's body and directly under her breast to create support for the breast and correctly position the breast for breastfeeding. A cover surrounds and conforms to the shape of the support member and may be removed for cleaning.
