Abstract: Systems and methods described herein may relate to a system including a plurality of industrial devices that each perform one or more operations within an industrial automation system having a plurality of hierarchical levels. Each of the plurality industrial devices may include a compute surface able to perform software tasks. The system may include a system of processors that receives trigger event data from a device corresponding to a first hierarchical level of the plurality of hierarchical levels. In addition, the system of processors is configured to identify a target device associated with additional data associated with the trigger event data, deploy a container to the target device, generate a data pattern based on the trigger event data and the acquired additional data, determine a remedial action associated with the trigger event data based on the data pattern, and instruct a device to implement the remedial action.

Abstract: A system for sensing subterranean acoustic waves emitted from an acoustic source includes a plurality of laser sources, a plurality of subterranean optical sensors, at least one optical detector, and electronics. The laser sources each emit light at a different frequency. The subterranean optical sensors receive the light and alter the light in response to the acoustic waves. The optical detector receives the altered light and outputs an electrical signal. The electronics receives the electrical signal and converts it into seismic data format. Preferably, the light emitted from the optical sources is modulated at a plurality of modulation frequencies. The electronics can be used to demodulate the signal. The electronics may demodulate the electrical signal by mixing the signal with periodic waveforms having frequencies corresponding to the modulation frequencies and twice the modulation frequencies.

Abstract: A retracting needle syringe is described which allows safe and easy disposal of a syringe and prevents re-use of the syringe by destroying the plunger rod and needle hub and retracting the needle into the plunger rod. Once the safety feature is activated, positive or negative pressure in the barrel to draw out medication is defeated. The retracting needle safety feature requires only an increase of force along the same line of action as the injection stroke. This allows for safe, one-handed injection, which is critical in some situations. The retracting needle syringe of the present invention also minimizes the amount of wasted medication because the plunger rod incorporates a plunger tip that occupies the entire volume inside the barrel. Because the retracting needle syringe uses standard luer-lok fittings, it can be used with a variety of standard needles that do not have retracting cannula.

Abstract: A surgical scalpel includes an elongate handle that has a proximal end, a open distal end and sidewalls that define an upwardly open cavity with a bottom with an open void therein. The sidewalls each have an elongate channel therein. The scalpel of the invention includes a cartridge that is removably retained within the cavity. The cartridge includes a shield. The cartridge has a blade holder with a proximal end and a distal end mounted within the shield for slidable movement between a proximal and a distal position. There is a latch on the blade holder for engaging the handle and the shield to retain releasably the blade holder in the distal position and the proximal position. The scalpel has a blade fixedly attached to the blade holder so that when the blade holder is in the distal position, the blade projects distally from the handle. When the blade holder is in the proximal position, the blade is within the shield and the handle and thus substantially protected from inadvertent exposure.

Abstract: A scalpel of the present invention includes an elongate handle defining a longitudinal axis and having a proximal end and a distal end. The scalpel of the invention further includes a cartridge that is removably mounted to the handle. The cartridge has blade holder with a proximal end and a distal end with a blade fixedly attached that is disposed so that the blade projects distally outwardly when the cartridge is mounted to the handle. The cartridge also includes a shield that is slidably mounted onto the blade holder for movement between a distal position where the shield substantially prevents inadvertent access to the blade and a proximal position where the shield substantially surrounds a portion of the handle and the blade is exposed for use. The cartridge is releasably mountable on the handle. The shield is substantially prevented from movement to the proximal position unless the cartridge is mounted on the handle and not dismountable from the handle unless the shield is in the distal position.

Abstract: A surgical scalpel includes a handle with a proximal end and a distal end that defines a cavity with an open distal end within the handle. The handle further includes an opening. The scalpel of the invention has a cartridge removably mountable to the handle. The cartridge includes a blade holder with a proximal end and a distal end. The blade holder includes elements for removably mounting the cartridge to the handle. There is a blade fixedly attached to the blade holder so that the blade projects distally. The scalpel of has a shield mounted on the blade holder for slidable movement between a distal position wherein the shield substantially prevents inadvertent access to the blade and a proximal position wherein the shield is substantially within the handle and the blade is exposed for use. The shield has a latch for engaging the blade holder and releasably retaining the shield in both the distal position and the proximal position.

Abstract: Light from a master laser is divided into multiple beams. Each of the beams is imaged onto a slave laser in a slave laser array. The multiple beams injection lock the frequency of each laser in the slave laser array to the frequency of the master laser. Some of the output light from the array of slave lasers is directed onto an optical wavefront measurement sensor which measures spatial variation in light phase and intensity. A computer responsive to the output of the optical wavefront measurement sensor controls the injection current to each laser in the slave laser array to adjust dynamically the relative phase of each laser in the array so as to synthesize a desired wavefront.
