A magnetic recording system containing magnetic recording media with separate data and servo magnetic layers is disclosed. A servo magnetic layer resides usually below the data layer and has higher coercivity than that of the data layer. Interference between the data and servo signals is minimized by recording the servo patterns perpendicular or transverse direction with respect to the orientation of data bits. In addition, servo patterns are selected so that no interference with the data is generated by the servo pattern when the reader is in the middle of data tracks. Tracking error signals are approximately linear with track misregistration around the middle of data tracks. Finally, interference between the data and servo signals is further reduced by electronic processing. Continuous servo signals permit increased track densities with a single actuator and very high track densities with dual microactuator-actuator system.

A transfer chair has a chair frame, a seat, wheels, and a lift arm which has an articulated path between home and target positions. The articulated path may define a limited clearance height to allow use with, e.g., cars having a small door opening. In one embodiment the seat is split and moves to allow passage of the lift arm as it travels along the articulated path. The lift arm is articulated such that a lifting bridle attached to a distal end of the lift arm is maintained in a constant angular orientation with respect to the chair frame during movement. The lift arm further has multiple deployment paths for target positions with different heights and distances. A transfer seat for the lift arm includes two flexible webs removably attached to the lifting bridle. The lift arm is constructed using four links which are pivotally connected end-to-end. The links can be folded to a stowed position within the chair frame. An actuation mechanism uses a lead-screw actuator coupled to one of the links which lifts the remaining links by rotation about its pivotal attachment to the chair frame, and similarly uses another lead-screw actuator coupled to the next link. The actuation mechanism can be operated by an on-board motion control computer for controlling the trajectory and velocity of the arm. Sensors provide trajectory information to the on-board computer, and a docking switch can select one of a plurality of target trajectories for deploying the lift arm. A docking station integrated with the frame mates with a docking feature on the target object and stabilizes the chair while transferring the user. The docking station may include a receptacle for electrical connection to a power supply. A more comprehensive transfer system is provided using a path sensor which tracks a sensible path proximate the target object, and an electronic controller responsive to the path sensor which operates the drive wheels to follow the sensible path to a stowage location. The transfer chair drive wheels may be caregiver-operated using throttle handlebars.

A plate-fin heat exchanger having a plurality of layers for indirectly exchanging heat between two or more fluids. The heat exchanger is provided with two sections and inlets and outlets to the sections to cause streams of the fluids to flow within the two sections parallel to the length of the heat exchanger between central locations and the ends of the heat exchanger. In such manner, the cross-sectional flow area of such a heat exchanger is greater than the heat exchanger in which the flow is from one end to the other end of the heat exchanger. This increase in cross-sectional flow area reduces the pressure drop within the heat exchanger.
