Abstract: Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member. The distal portion of the wing can define a bone anchor opening through which one or more auxiliary bone anchors can be disposed to augment the fixation of the assembly's primary bone anchor. A distal surface of the distal portion of the wing can be obliquely angled relative to a proximal-distal axis of the spanning portion to face one of a caudal direction or a cephalad direction. A distal surface of the distal portion of the wing can be obliquely angled relative to the proximal-distal axis of the spanning portion to face one of a medial direction or a lateral direction. Surgical methods using the bone anchor assemblies described herein are also disclosed.

Abstract: A method is disclosed. In various examples, the method may include receiving an instruction for generating a signal comprising a ranging signal and a data signal. The method may also include transmitting, via a terrestrial transmitter for transmitting radio waves having encoded messaging information and timing information for one or more of positioning, navigation and timing, the signal at least partially responsive to the instruction. The signal may include a pulse group comprising a number of ranging pulses and a number of data pulses subsequent to the number of ranging pulses. Respective ones of the number of data pulses may have a phase of either a positive-going phase or a negative-going phase. Information may be encoded using the either positive-going phases or negative-going phases of the data pulses.

The syringe pump including a syringe pump housing defining a syringe receptacle shaped and sized to accept loading of the syringe, a plunger driver assembly configured to manipulate a plunger of a syringe loaded into the syringe pump, and a syringe housing including a syringe barrel shield pivotably coupled to the syringe pump housing configured to at least partially enclose a syringe loaded into the syringe pump within the syringe receptacle, and a syringe plunger tray and lid assembly operably coupled to the syringe pump housing and configured to at least partially enclose a portion of the plunger driver assembly.

Abstract: Ladders and ladder components are provided including a rung assembly that provides an alert to a user of the ladder that they are standing on a particular rung or step. In one example, the lower most rung or step of a ladder includes a rung assembly having an alert mechanism. The alert mechanism may provide an audible and/or other sensory alert to a user when they step on the rung assembly so that the user recognizes their position relative to the ground or supporting surface. In one embodiment, the rung assembly is configured such that a front edge remains in a constant or fixed position relative to the rails to which it is coupled so that a user can rely on a fixed or constant position of the front edge of the assembly when climbing or descending the ladder.

Abstract: A method is disclosed. In various examples, the method may include receiving an instruction for generating a ranging signal, and transmitting the ranging signal at least partially responsive to the instruction. In various examples the ranging signal may be transmitted via a terrestrial transmitter for transmitting radio waves having encoded messaging information and timing information for one or more of positioning, navigation and timing. In various examples, the ranging signal may exhibit a first ranging pulse and a second ranging pulse of a pulse group and an encoded transmitter identifier, the transmitter identifier encoded by modulating an inter-pulse interval defined between a start of the first ranging pulse and a start of the second ranging pulse.

Abstract: A device is disclosed. In one or more examples, the device may include an antenna to receive a signal comprising a ranging signal and a data signal. The signal may encode timing information for one or more of positioning, navigation, and timing. The signal may include a first pulse having a first start time and a second pulse having a second start time. The second start time may be an integer number of inter-pulse intervals plus an encoding delay after the first start time. The encoding delay may encode data. The device may include a processor to obtain the data responsive to the encoding delay.

Abstract: A moving magnet motor with a stator comprising first and second spaced coil-wound cores that each have a width, the cores separated by an elongated gap, and an elongated magnet located at least in part in the gap and lying generally along a motor depth axis that is in the gap and is generally uniformly offset from the cores, where the magnet has poles. The motor has a width axis that is perpendicular to the depth axis and is generally uniformly offset from the cores. The magnet has a width along the motor width axis and the cores each have a width along the motor width axis. Along the motor depth axis the ratio of the width of the magnet or a pole of the magnet to the width of a core varies.
