A method for evaluating voltage sensor output using a diagnostic system includes: measuring an overall fuel cell stack voltage using a stack voltage sensor; identifying a fuel cell voltage of a first end cell using a first end cell voltage sensor and a second end cell using a second end cell voltage sensor; determining if a maximum value of the overall fuel cell stack voltage, the fuel cell voltage of the first end cell or the second end cell is less than a sensor limit, and if a minimum value of the fuel cell voltages is greater than the sensor limit; performing a test to identify if the maximum value is greater than an average sensor signal value and if the average sensor signal value is greater than the minimum value; and conducting a test to identify if the minimum value is less than a first predetermined threshold.

A fuel cell charging system includes a fuel cell stack having a first operating direct current (DC) voltage between fuel check stack terminals, a high voltage system operating at a first DC operating voltage different than and generally higher than the first operating voltage of the fuel cell stack, a boost converter in electrical connection with the fuel cell stack and the high voltage system, and a stack charging component that applies a second DC operating voltage, generally of lower value than that of the first normal operating voltage, to the fuel cell stack. The boost converter transfer electrical power from the fuel cell stack to the high voltage system during fuel cell operation. Characteristically, the second DC operating voltage applied to the fuel cell stack terminals is typically lower in value than that of the first DC operating voltage of both the fuel cell stack and the HV electrical system and is stepped down from the first DC operating voltage of the HV electrical system.

Apparatus and method to apply voltage to fuel cell stack from high voltage system for usage during diagnostic tests

A fuel cell voltage recovery system includes a fuel cell stack having a fuel cell stack voltage between fuel cell stack terminals which is at a first voltage during normal fuel cell operation. The system also includes a high voltage electrical system operating at a first DC operating voltage that is generally higher than the first voltage of the fuel cell stack. A boost converter in electrical connection with the fuel cell stack and the high voltage electrical system operates in a normal control mode to transfer electrical power from the fuel cell stack to the high voltage electrical system through regulation and control of average stack output current (boost input current) during normal fuel cell operation. The boost converter can also operate in a voltage control mode to lower the fuel cell stack voltage to a second voltage that is lower than the first voltage. A FCS controller controls the operation of the boost converter.

Methods and systems for identification of slave elements and/or cells in a communication system within a vehicle. In some implementations, such methods may comprise measuring a first voltage of a first slave device of a plurality of slave devices within the communication system, and measuring a second voltage of a second slave device of the plurality of slave devices within the communication system. A location of at least the first and second slave devices, which may be linked with respective cells, such as battery cells or fuel cells, may then be identified by comparing at least the first voltage with the second voltage.

A seat construction corrects the pelvis so that it influences a proper alignment of the body. The seat construction has at least four independent seat assemblies which are supported by a base plate. Each seat assembly includes a frame shaped support affixed to the base plate, a rigid support plate affixed to the top of the frame shaped support, and a full foam seat cushion affixed to the top of the support plate. In an alternative embodiment, the seat construction has at least four independent seat assemblies which are supported by a base plate. Each seat assembly includes a frame shaped support affixed to the base plate, a rigid support plate affixed to the top of the frame shaped support, and a full foam seat cushion affixed to the top of the support plate. Each seat assembly further includes at least three springs embedded within the frame shaped support for further supporting the weight of an individual to improve the posture of the individual by more efficiently supporting the weight of the individual who sits on the seat construction and adjusting the height of the independent seat sections to accommodate movement of the individual sitting in the seat construction.

An improvement to a seat having relatively adjustable sections to improve the rocking means of each separate seat section to move back and forth in a longitudinal rocking, move downwardly and sliding backwardly, to thereby more effectively and efficiently assist in the comfort of the individual. The improvement includes a seat rocking member such as an arch shaped suspension affixed to the lower portion of each seat half and affixed at only one side to the upper surface of the base. The resilience of the arch shaped suspensions permits and limits the seat to move downwardly and slide backwardly, when a force such as the weight of a person pushes downwardly on the seat. The resilience of the arch shaped suspensions further permits and limits the seat to rock back and forth to thereby enable the user to independently rock back and forth in a front to back rocking arrangement on each seat half.

Rocking seat

An improvement to the seat having relatively adjustable sections disclosed and claimed in U.S. Pat. No. 3,749,442 to restrict the movement of each separate seat section to movement only back and forth in a longitudinal rocking motion as opposed to universal movement, to thereby more effectively and efficiently assist in the comfort of the individual and adjustment of the seat to movements of the user without causing undue fatigue over time. The improvement includes a seat rocking member such as a cylindrical rod affixed to the lower portion of each seat half and a pair of spaced apart resilient receiving members for each seat half to movably and rotatably support a seat half on the base of the seat. The resilience of the receiving members permits the the seat rocking members to vertically move downward within the receiving members when a force such as the weight of a person pushes downward on the seat. The resilience of the receiving members further permits the seat rocking members to rock back and forth to thereby enable the user to independently rock back and forth in a front to back rocking arrangement on each seat half. An adjustable device limits the amount of front to back rocking which can be created.

A biophysiometer having two seat sections which support the right and left sides respectively of a person's body, and are adapted for relative vertical movement and relative tilting movement to positions displacing the two sides of the body relative to one another in a manner tending to correct an abnormal posture condition or otherwise attain a desired treatment effect. The two seat sections are preferably supported by a balancing connection operatively interconnecting them in a relation in which downward movement of one of the sections causes upward movement of the other section, and vice-a-versa. Desirably, the apparatus includes automatic control means which respond to displacement of the two seat sections relative to one another by the weight or positioning of a person's body, and then automatically actuate the seat sections to changed relative positions tending to correct the posture or other abnormal condition sensed by the device.

Orthopedic instrument having relatively adjustable seat sections

A seating unit with a flexible seat back having an upper portion separated into two halves positioned to support a user's back at opposite sides of his spine, and with these halves being mounted for resiliently resisted rearward deflection relative to one another in order to accommodate movement of the user's body, and with a slit or the like being provided at the center of the back between these halves to enable projection of the user's spine rearwardly beyond adjacent portions of the user's back for optimum comfort at all times. The back structure may be connected to a generally horizontal seat element, which may be bifurcated to have two relatively movable forwardly projecting portions. The device may also have an anchoring portion for detachable connection to a cushion of an upholstered seat on which the unit is to be used.
