  • Patent number: 8745781
    Abstract: A crib is provided that includes a drop gate that pivots relative to a stationary portion of a wall from an open position to a closed position. The crib may include a hinge that in the closed position of the drop gate forms a cavity therein that has a height that is sufficiently large to enable a finger of a child to extend into the cavity to be adjacent a pivot axis of the hinge, without being pinched by the hinge. Also, the crib may include a stop surface of a latch device that contacts a projection in a cavity of a striker plate to prevent pivoting of the drop gate into an interior space of the crib. The cavity in the striker plate may include sufficiently large spaces above and below the projection to receive a finger of a child therein without the finger being pinched.

  • Patent number: 8613480
    Abstract: A child restraint system for use in a vehicle having improved vehicle seat belt anchoring mechanisms and an improved reclining mechanism. The vehicle seat belt anchoring mechanisms include a lap belt anchoring rod that is pivotable to facilitate the routing of the lap belt independent of the shoulder belt of the vehicle restraint system. The shoulder belt anchor member is located higher on the seat, and includes an anchor member received in a channel in the seat back. The recline mechanism of the child restraint system includes a recline plate that is connected to the rigid latch members. Reclining of the seat body results in movement of the rigid latch members to allow room between the seat body and the vehicle seat, thereby allowing adjustment of the recline angle of the seat without necessitating removal of the seat from the vehicle.

  • Patent number: 8424964
    Abstract: A child safety seat includes a base, a seat body, a dampening member, and a non-planar impactor. The seat body is slidably secured to the base and is movable between a pre-collision position and a post-collision position. The dampening member is positioned between the base and the seat body. The non-planar impactor is secured to the seat body and is positioned to engage the dampening member. The non-planar impactor and the dampening member together provide a progressive dampening force against movement of the seat body from the pre-collision position to the post-collision position.

  • Patent number: 8226162
    Abstract: A child safety seat includes a headrest assembly that is vertically adjustable. The headrest assembly includes a release member accessible from the front of the seat and a shoulder belt support member that is secured to the release member and movable therewith. The child safety seat also includes a base and a seat body that is movable relative to the base. A force dampening system progressively absorbs forces acting upon the child safety seat as the seat body moves relative to the base. A latch release assembly is also provided to disengage clamp members from lower attachment hooks in a vehicle, the release assembly including a release lever accessible from the front of the car seat.

  • Patent number: 6512463
    Abstract: A protocol for utility meter interrogation has a data write portion including: assembling a password transmission sequence having a synchronization string and a message including identification indicia for a select utility meter and a password to activate a select data access level within the select utility meter. This is wirelessly transmitted a first time to a select utility meter. Then, the password transmission sequence is wirelessly transmitted a second time to the select utility meter to confirm the password transmission sequence. A command transmission sequence having the synchronization string and a message including the identification indicia and a write command is assembled to cause the select utility meter to store data in a memory location of the select utility meter corresponding to the data access level activated with the password. The command sequence is then wirelessly transmitted to the select utility meter two times to confirm the command transmission sequence.

  • Patent number: 6304191
    Abstract: The present invention provides a unidirectional protocol for communicating data from a plurality of utility meters and a meter adapted to carry out this protocol. The meters are adapted to monitor and measure the respective utility parameters which may include those for gas, water, electric or other utilities, and wirelessly download the information to a meter reading device. The protocol basically includes a synchronization pattern followed by the desired information. For a valid transmission, the synchronization pattern and subsequent data are provided in a first transmission sequence, which is immediately repeated after the end of the first sequence. Preferably, a bit is toggled during the retransmission of the transmission sequence for security.

  • Patent number: 6060926
    Abstract: The present invention relates to a pulse conditioning circuit including a first switch terminal having a first leg connected to a DC power source and a second leg. A second switch terminal is also provided having a first leg connected to an electrical ground and a second leg electrically connected to the second leg of the first switch. Pulses resulting from switch closures at the switch terminals are provided at the node where the second legs of both switch terminals are coupled. This node is preferably coupled to a low-pass filter, which is further coupled to a latch circuit providing a conditioned pulse output. The latch circuit is adapted to provide a first logic state output when the input of the latch is provided with a high logic state and a second logic state output when the input of the latch is provided with a low logic state. The high logic state input is provided when a switch connected to the first switch terminal is closed.

  • Patent number: 4993027
    Abstract: Method and apparatus for testing the address/data paths between the ROM and CPU of a computer where the computer includes a first connector adapted to connect the ROM to the address/data paths so that data can be transferred between the CPU and the ROM via the data paths of the address/data paths and a second connector adapted to connect the CPU to the address/data paths so that addresses can be applied to an address decoder for the ROM via the address lines of the address/data paths. A memory is connected to the address decoder and the data lines via the first connector, the memory storing predetermined data at a plurality of memory locations. A kernel debugging module connected to the address/data paths via the second connector includes circuitry for successively applying read signals which emulate those provided by the CPU to successively read the predetermined data stored at the memory locations.
