Abstract: Described herein are methods for controlling the release of nitric oxide from a nitric oxide releasing material. The method involves exposing the nitric oxide releasing material to light having a discrete wavelength, wherein the nitric oxide releasing material comprises a (i) a polysiloxane network and (ii) a plurality of nitric oxide-donating moieties covalently bonded to the polysiloxane network. The tunability of nitric oxide release from the nitric oxide releasing materials described herein provides unique therapeutic profiles that correspond to endogenous thresholds of nitric oxide for desired physiological response. The methods described herein can prevent bacterial growth as well as the formation of biofilms and fibrinogen on articles such as, for example, medical devices.

Abstract: A power supply system for supplying power to a load of an electronic apparatus includes first and second battery units, and a selector coupled to the load and the first and second battery units. The selector is operable so as to break electrical connection between the second battery unit and the load and to simultaneously make electrical connection between the first battery unit and the load when a remaining capacity of the first battery unit is higher than a predetermined reference value, and so as to break electrical connection between the first battery unit and the load and to simultaneously make electrical connection between the second battery unit and the load when the remaining capacity of the first battery unit is lower than the predetermined reference value. A controller coupled to the selector, is responsive to a first control command, which may be issued by the electronic apparatus, so that the controller overrides the detector and enables operation of the selector in the first state.

Abstract: A portable electronic apparatus includes first and second modules, and a control unit. The first module includes a first charging circuit to be coupled to a first power source, and a first battery unit coupled to the first charging circuit. The second module is connected removably to the first module, and includes a second charging circuit to be coupled to a second power source, and a second battery unit coupled to the second charging circuit. The control unit enables the first and second battery units to be charged independently and respectively through the first and second charging circuits using the first and second power sources when the second module is disconnected from the first module, and enables the first and second battery units to be charged through the first charging circuit using the first power source when the second module is connected to the first module.

Abstract: A power management method for an electronic apparatus powered by a battery unit and installed with an operating system includes the steps of inputting a user-defined remaining capacity for the battery unit into the electronic apparatus, and reporting the user-defined remaining capacity to the operating system. The operating system supports a power management specification and is operable so as to obtain an actual remaining capacity of the battery unit. When the operating system compares the user-defined remaining capacity with a reference value according to the power management specification, and determines the user-defined remaining capacity to be lower than the reference value, the operating system enables operation of the electronic apparatus in a low power consumption mode.
