16. A patient bed comprising:
-
a base;
a patient support;
an elevation mechanism for raising or lowering said patient support relative to said base; and
a control system, said control system including one or more actuators for activating said elevation mechanism to raise or lower said patient support relative to said base, said control system being powered by (1) an external power supply or (2) at least one battery, when powered by the external power supply said control system operating said one or more actuators independent of the battery, and when powered by the battery said control system operating said one or more actuators independent of the external power supply. - View Dependent Claims (17, 18, 19)

20. A patient bed comprising:
-
a base;
a patient support movable supported relative to said base; and
an angle sensor mounted to a component of said base or said patient support, said angle sensor measuring an angle of said component based on gravity wherein said angle sensor may detect the angular orientation of said component independent of any frame of reference other than gravity. - View Dependent Claims (21, 22, 23, 24)

- 48. The patient bed according to claim 48, wherein said touch screen displays a function selected from a group consisting of apparatus motion, mattress air pressure, patient motion, patient biometrics, patient information, patient weight, bed security, alerts, exit and event log/history, help screens, diagnostics, run lights, and open doors or windows, and motion sensing.

58. A patient bed comprising:
-
a base;
a support frame system;
a driver system for moving at least a portion of said support frame system;
a control system, said control system including one or more limit switches for detecting a maximum range of motion of at least one portion of said support frame system to thereby limit movement of said portion.

-
59. A patient bed comprising:
-
a base;
a patient support configured to be moveably supported by said base, said patient support having a first end and a second end, each of said ends having an elevation;
first and second drive mechanisms capable of operating at variable speeds for selectively adjusting said patient support relative to said base, said first drive mechanism controlling said elevation of said first end of said patient support and said second drive mechanism controlling said elevation of said second end of said patient support, said first drive mechanism configured to initially operate at a first maximum operating speed and said second drive mechanism configured to initially operate at a second maximum operating speed that is substantially equal to said first maximum operating speed;
at least one angle sensor located on said patient support for determining an angle of inclination of said patient support; and
a control unit for selectively controlling the elevation of said patient support, wherein during a change in elevation of said patient support, said control unit repeatedly compares a starting angle of inclination of said patient support to a pre-set angle of inclination of said patient support, and if not substantially equal, adjusts the operating speed of one of said drive mechanisms to compensate.
-
-
60. A method of changing an elevation of a patient support subject to an uneven distribution of load while maintaining an angle of inclination of said patient support, said method comprising the steps of:
-
determining a first angle of inclination of said patient support by means of at least one angle sensor located on said patient support;
activating first and second drive mechanisms configured to change an elevation of first and second ends of said patient support, respectively, said first and second drive mechanisms configured to initially operate at substantially equivalent maximum speeds;
determining a present angle of inclination of said patient support by means of said at least one angle sensor;
comparing said first angle of inclination to said present angle of inclination, and if not equal, adjusting the speed of one of said drive mechanisms to compensate;
determining whether said patient support has obtained a desired elevation;
repeating said determination of present angle of inclination step and comparing step until said desired elevation is obtained; and
stopping said drive mechanisms upon obtaining said desired elevation. - View Dependent Claims (61)
