    Abstract: Described embodiments relate to improved methods and systems for computationally efficient optimization of radiation dose delivery. The optimization involves determining an improved form of objective function to be used for mapping radiotherapy beams to a patient body volume having at least one target volume and at least one non-target volume. The objective function has a first term related to the at least one target volume and a second term related to the at least one non-target volume. The optimization further involves determining a minimum of the objective function, whereby beams, comprising a plurality of beamlets, mapped to pass through the at least one non-target volume, comprising a plurality of non-target volume portions, are limited such that the second term is zero only if, a product of the intensity of a beamlet mapped to pass through a non-target volume portion and the dose deposited by said beamlet is equal to a first predetermined average dose constraint value for the respective non-target volume portion, for all beamlets mapped to pass through the at least one non-target volume. This limit aims to reduce the occurrence of negative beam weights, thereby facilitating computationally efficient determination of the minimum of the objective function and achieving more physically realistic beamlet intensities. In another embodiment, the objective function has a smoothing term for biasing the intensity of beamlets, for a respective beam mapped to pass through the at least one target volume and the at least non-target volume, towards a uniform distribution within the respective beam. Following the optimization, radiotherapy is delivered based on the determined minimum of the objective function.

The objective function has a first term related to the at least one target volume and a second term related to the at least one non-target volume.

This limit helps to avoid the occurrence of negative beam weights, thereby facilitating computationally efficient determination of the minimum of the objective function using matrix inversion. Following the optimization, radiotherapy is delivered based on the determined minimum of the objective function.

    Abstract: A special BIOS includes a program application manager (PAM) and a file system structure (FSS) that points to addresses on a mass storage device (MSD) for an application and at least one presentation playable by the application. The BIOS calls the PAM on startup, and the PAM checks for an application, and finding same loads and executes the application before loading the operating system (OS). In a preferred embodiment the FSS is programmable, and the system after OS boot is started checks MSD devices for new FSS parameters, and finding same loads the parameters to the programmable FSS of the BIOS. In some embodiments parameters may cause presentations and associated applications to be accessed and executed in a rotating or serial order. In other embodiments the BIOS represents its own address space in RAM to the OS at OS boot to include the application, enabling the application to continue to execute during OS boot. In further embodiments a special driver is executed after OS boot to bind the application into the OS configuration so the application may continue to operate in a stable manner.

    Abstract: A dry powder inhaler has a slider for incrementally advancing a blister disk, to provide successive doses of a dry powder pharmaceutical. A blister disk is rotatably supported on a spindle on a deck plate of the inhaler. A powder port, an advancing slot, and a lifter slot extend through the deck plate. A slider is attached to the deck plate and movable between open and closed positions. As the slider is opened, a litter moves up on a ramp on the slider to shear open a blister, so that the blister contents can be mixed with air and inhaled. As the slider is moved back to the closed position, the lifter is withdrawn and an advancing finger turns the disk to bring the next blister into position for opening to provide the next dose to the patient.

    Abstract: A door lock has a lock latch, a first locking mechanism and a second locking mechanism. The first locking mechanism and the second locking mechanism can be relatively screwed and assembled with the lock latch. When the second locking mechanism is assembled relative to the first locking mechanism, the upper guide rail and the lower guide rails of the lower guide plate of the second locking mechanism are respectively embedded in the upper guide groove and the lower guide grooves of the first locking mechanism, and the internal thread portion of the second locking mechanism is relatively threaded with the external thread portion of the first locking mechanism. In addition, with the design of the internal thread portion and the external thread portion having the inner shaft moving surface and the outer shaft moving surface, respectively, the speed of threaded movement is faster when they are threaded together.
