20130091961 | PRESSURE SENSING MAT - A pressure sensing sheet includes at least first, second, and third layers wherein the first and third layers each have conductive paths defined therein that are separated by nonconductive spacers. The orientation of the conductive paths of the first layer are transverse to the orientation of the conductive paths of the third layer. The second layer is made of material that has an electrical characteristic that changes with applied pressure, such as, but not limited to, piezoresistive or piezoelectric material. The first and/or third layers are made from multi-material sheets wherein a first type of material will repel conductive particles when subjected to an autocatalytic coating process, while the second type of material will bond with the conductive particles during the autocatalytic coating process. The use of different materials in the first and/or third layers facilitates the manufacturing of the conductive paths and nonconductive spacers. | 04-18-2013 |
20130113057 | FORCE SENSING SHEET - A force sensing array includes multiple layers of material that are arranged to define an elastically stretchable sensing sheet. The sensing sheet may be placed underneath a patient to detect interface forces or pressures between the patient and the support structure that the patient is positioned on. The force sensing array includes a plurality of force sensors. The force sensors are defined where a row conductor and a column conductor approach each other on opposite sides of a force sensing material, such as a piezoresistive material. In order to reduce electrical cross talk between the plurality of sensors, a semiconductive material is included adjacent the force sensing material to create a PN junction with the force sensing material. This PN junction acts as a diode, limiting current flow to essentially one direction, which, in turn, reduces cross talk between the multiple sensors. | 05-09-2013 |

20130131680 | SURGICAL SAGITTAL SAW BLADE WITH A BIASING ASSEMBLY THAT URGES THE BLADE ASSEMBLY USED WITH THE SAW AWAY FROM THE SAW HEAD - A surgical sagittal saw for use with a complementary blade assembly that includes a static bar. The saw includes a head over which the blade assembly bar is seated. A biasing member mounted to the saw head normally places a force of the blade assembly bar that urges the bar away from the blade head. A coupling assembly releasably holds the blade assembly bar in the static state to the saw head. When the coupling assembly is in the run state, holding the blade assembly to the saw head, the coupling assembly does so in opposition to the force the biasing assembly exerts against the blade assembly bar. During the process of removing the blade assembly from the saw, the force of the biasing assembly assists in the removal of the blade assembly bar from the saw head. | 05-23-2013 |

Each armrest may include a locking mechanism for holding the armrests in a use position. When locked in the use position, a user may apply an upward force on the armrests to lift the chair upwardly that does not cause pivoting of the armrests. The chair is designed to allow nesting with other chairs of similar design. The front wheels may be positioned laterally apart a greater distance than the rear wheels to allow a first chair to nestingly receive a rear portion of a second chair. Foley hooks may also be included on the chair for hanging a Foley catheter bag. | 06-06-2013 |
20130140783 | BRAKES FOR MOBILE MEDICAL DEVICE - A brake system for a medical device, such as a cot, stretcher, bed, wheeled chair, or other medical device, includes a pin and toothed wheel arrangement wherein the selective insertion of a pin between teeth on the toothed wheel brakes the system, while the removal of the pin from between the teeth unbrakes the system. Multiple pins may be used with a single toothed wheel wherein the pins are offset from each other relative to the teeth so that, when one pin is inserted between teeth, the other pin is at least partially blocked from being inserted between the teeth. This effectively increases the resolution of the toothed wheel. The toothed wheel may be axially spaced from wheel(s) that roll on the ground. When so spaced, the toothed wheel, and all of the braking components associated therewith, may be enclosed within a housing separate from the rolling wheel(s). | 06-06-2013 |
20130140788 | WHEELED PATIENT SUPPORT WITH FOOT RESTS - A wheeled chair for transporting patients includes a plurality of footrests for supporting a patient's feet thereon. Each footrest is pivotable between an up position and a down position, and includes a biasing mechanism for biasing the footrest toward the up position, or the down position, or whichever of the two positions the footrest is currently closer to. A swing mechanism swings the footrests from a use position in front of the seat to a stowed position alongside the seat. A trigger, such as a button, automatically activates the swinging. The swinging may take place about a vertical axis that is common to the axis about which the front caster wheels swivel. Pivot extensions may be included on the footrests that provide a tool for enabling a caregiver to manually pivot the footrest between the up and down positions with his or her foot. | 06-06-2013 |

The leg rest includes a latch and a handle for releasing the latch. The latch is adapted to automatically retain the leg rest in whichever of the use and stowed positions it currently is in. Pulling on the handle releases the latch and allows the leg rest to be moved between the use and stowed positions. The leg rest includes a pad that is positioned, when the leg rest is in the use position, to contact a patient's calf. The leg rest is configured to both pivot about a pivot axis and to have two different sections that translate with respect to each other. | 06-06-2013 |
