The assembly includes, among other elements, a filter holder for securing a HVS filter within the assembly, a desorber body, and an insulating enclosure. The design of the thermal desorber assembly is such that it can accommodate a variety of different types of HVS filter media. Also described herein is a system comprising the thermal desorber assembly and method of using the assembly.

Abstract: An unmanned aerial vehicle may include a fuselage and an anchor structure coupled to the fuselage and including a wing retention structure and a power module retention structure. The unmanned aerial vehicle may also include a wing releasably coupled to the wing retention structure, thereby coupling the wing to the fuselage, and a power module releasably coupled to the power module retention structure, thereby coupling the power module to the fuselage.

Abstract: A configurable modular robotic autonomous guided vehicle having an engine module and multiple different ones of selectably interchangeable logistic or material handling accessory modules. The engine module has motors, sensors and a control system integrated with each other for autonomous navigation freely throughout a travel area forming a logistic space. A module interface is located at one end of the engine module for modular coupling of the engine module with a handling accessory module of the vehicle. Each of the handling accessory modules has a different predetermined logistic or material handling characteristic that on integral coupling with the engine module define a different logistic or material handling autonomous guided vehicle type. Selectable coupling of the handling accessory module with the engine module configures the vehicle so as to change the vehicle type from a first vehicle type to a second vehicle type different than the first vehicle type.

Abstract: A method and apparatus for use in controlling a dispensing rate of medication or other substance via a syringe, including, without limitation, into a patient, intravenous line port or heparin lock. A fluid flow rate control apparatus has a housing defining an inner chamber with an inlet port and an outlet port. Sealing seats are formed at or near both the inlet and outlet ports, and a moveable sealing element, such as a ball, can move within the inner chamber between the sealing seats. A spring biases the ball toward the inlet port sealing seat.

Abstract: A method of generating an output log for analysis of a computer program, the method comprising: receiving a recording of an execution of the program; receiving an additional print instruction to print a value of a data item and an indication of a point in the program at which the additional print instruction is to be evaluated; determining a corresponding point in the recording of the execution based upon the indication of the point in the program; and evaluating the additional print instruction based upon the recording of the execution and the determined corresponding point to determine an output of the additional print instruction for insertion into the output log.

Abstract: A biodegradable lawn waste collection system is provided. The system generally includes a waste receiver, a shaping insert, and a handle. The waste receiver may comprise a mesh structure having a filling end and a sealing end. The mesh structure may be formed from a biodegradable polymer composition. The shaping insert is configured for removable reception within the filling end of the waste receiver. The shaping insert provides the waste receiver with rigidity and stability when filling the waste receiver with lawn waste. After the waste receiver has been filled with lawn waste, the shaping inert is removed and the filling end is secured, such as by tying a knot. The full waste receiver is then releasably attached to the handle, which enables the full waste receiver to be easily carried or dragged to a desired destination.
