Abstract: A computer-implemented image processing technique for selectively recovering the features of an original CAD model after the original CAD model has been converted to a digitized image and a new CAD model generated from the digitized image. The original boundary representation provides a template to transform the representation through processing under governance of a programmed processor so as to recover accuracy and reintroduce feature edges and feature corners as well as other detailed features to the CAD model obtained from the digitized image, e.g., to enable detailed features to be retained that would otherwise have been lost due to the lossy conversion into image space. The method operates to better ensure that reconstructed boundary vertices lie on original CAD model surfaces and feature edges and corners are recovered.

Abstract: The present application relates to a class of switching power supplies, which use a resonant isolation stage (typically LLC) fed directly or via a diode bridge from the line. Extension of the range of available gain values over frequency without material loss of efficiency is facilitated by usage of additional resonant elements. This capability allows the devices to provide narrow-range inputs to secondary-processing circuits, with the ability to achieve power factor correction if required. The conversion architecture is also compatible with optimal usage of energy storage elements suitable for use with switching power supplies.

Abstract: A dedicated needle assembly (300) that can be attached only to a dedicated drug delivery device (400) is disclosed. The dedicated needle assembly (300) comprises a connecting body (320) extending from a distal end to a proximal end. A dedicated mechanical coupling (310) is configured at the proximal end of the connecting body (320). The dedicated mechanical coupling (310) forms a releasable connection to a distal end of the dedicated drug delivery device (400). The dedicated needle assembly (300) may comprise a medicated module or, alternatively, a non-medicated module. In one arrangement, the dedicated mechanical coupling (310) is integral with the dedicated needle assembly (300).

Abstract: A medicated module for an injection system to co-deliver at least two medicaments is disclosed where a primary delivery device containing a primary medicament accepts a medicated module containing a single dose of a secondary medicament and where both medicaments are delivered through a hollow needle. The medicated module is user selectable so that it will deliver a priming dose of a primary medicament or both the primary and secondary medicaments. The module also contains a needle guard that locks after dose delivery. The needle guard prevents accidental needle sticks before and after an injection. A locking collar rotates during use as an inner protrusion follows three paths of a track located on the outer surface of a body housing. When the inner facing protrusion is in the third path, it encounters a hard stop and a rotational bias that locks the guard from further refraction and thus covers the sharp distal end of the needle.

Abstract: A medicated module includes (i) a rotatable reservoir body comprising (a) a flow path and (b) a medicament-reservoir profile and (ii) a pin feature disposed in the rotatable reservoir body, the pin feature comprising a medicament-cavity profile. The medicated module also includes a second medicament, wherein the second medicament is held in a reservoir formed at least in part by the medicament-reservoir profile and the medicament-cavity profile, and wherein, prior to dispense, the second medicament is filled to at least the proximal end of the medicament-cavity profile.

Abstract: A reservoir assembly for a medicated module includes a primary cavity for holding a medicament, a sump region, and a flexible element. The flexible element is configured to allow for fluid communication between the primary cavity and the sump region during a filling process for the reservoir. Further, the flexible element is configured to prevent fluid communication between the primary cavity and the sump region after the filling process.

Abstract: A medicated module containing a second medicament is configured for removable attachment to the mouthpiece of an inhaler containing a first medicament such that a single inhalation by a user will deliver both medicaments to the user.

Abstract: To make more efficient use of storage capacity, a non-volatile storage system will store system data on marginal word lines. In one embodiment, a marginal word line is a word line that is not suitable to store host data because it is not sufficiently reliable for properly programming and reading the host data.

Abstract: A non-volatile memory system includes a memory section having a non-volatile cache portion storing data in a binary format, a primary user data storage section that stores user data in multi-state format, and an update memory area where the memory system stores data updating user data previously stored in the primary user data. The memory system allows a maximum number of blocks for use in the update memory area. When the memory system receives updated data corresponding to user data already written into the primary user data storage section, it determines whether a block of memory is available in the update memory area. In response to determining that a block of memory is not available in the update memory area, the system determines a block of the update memory to remove from the update memory; copies the data content of the determined update block into the cache portion of the memory section; and subsequently writes the updated data into the update memory.

A switch driver stage configured to provide each of a first control signal and a second control signal based on the PWM signal. A switching stage comprising a first transformer input stage, a second transformer input stage, and a control switch. The first transformer input stage activates the control switch via the first control signal while the second transformer input stage is deactivated, and the second transformer input stage activates the control switch via the second control signal while the first transformer input stage is deactivated. The control switch can be configured to provide current through an output inductor in the output stage to generate the output voltage in response to being activated.
