摘要:
A controller for a DC to DC converter with reference voltage loop disturbance compensation. The controller may include an error amplifier configured to receive a first signal representative of an actual output voltage of the DC to DC converter and a reference signal representative of a desired output voltage of the DC to DC converter and to provide an error signal representative of a difference between the first signal and the reference signal. The controller may also include a PWM modulator with reference voltage compensation circuitry configured to receive the error signal and compensate for a change in the reference signal in order to control overshoot and undershoot of the actual output voltage from a desired voltage due to the change of the reference signal. An electronic device and method are also provided.
摘要:
An over voltage protection circuit for single phase and multiphase buck converters. According to one embodiment, upon the occurrence of an over voltage condition, the high side switch is turned Off and the low side switch is On. As the output voltage drops below a lower threshold, the low side switch is turned Off thereby reducing or eliminating negative spikes on the voltage output.

A device (1) for controlling user access to at least one container (4) for dispensing printing material housed by a printing apparatus (5), the device (1) comprising an openable and closable barrier (2) corresponding to the container (4) and a lock for locking the barrier (2) in a closed position. The lock is overlapped by at least a portion of the barrier (2) both when the barrier (2) is in the closed position and when the barrier (2) is in an open position.
摘要:
A Horizontally-Linked Reinsurance Network (HLRN) formed of a plurality of small insurance companies (as defined by applicable law, e.g. U.S.C. §831(b)) that is established and managed by a network administrator presents a new approach to harnessing the benefits of small insurance companies while mitigating the drawbacks of small insurance companies. This system uses a rules-based approach and algorithm to select, allocate, optimize and manage the individual risk portfolio of independent small insurance companies so as to preserve their status as a small insurance company while diversifying risk. Further, network administrator will perform the management functions if the HLRN. This allows investors or persons who would not otherwise own an insurance company to invest in a new asset class which by its nature demonstrates a non-correlation to traditional investment markets and carries both unique return and tax properties.

The described invention provides methods for treating or preventing progression of a progressive cognitive disease, disorder or condition, and methods for improving resilience of cognitive function in a subject in need thereof.
摘要:
An impact and/or vibration absorbent material and protective articles making use of said material. An impact and/or vibration absorbent material of the present invention has at least two material layers. The individual layers of the impact and/or vibration absorbent material may be of different materials, or of the same material with the composition of the material of one layer adjusted to be of dissimilar hardness to an adjacent layer. Each material layer preferably contains a number of holes. The holes in one layer are located and arranged to be offset from the holes in an adjacent layer. The combination of material properties and the inclusion and arrangement of holes renders such a material highly impact and/or vibration absorbent. Through use of a protective article of the present invention, the effects of impact and/or vibration forces on a user of the protective article can be minimized.
