Abstract: A notification system automatically sends notifications to users based on the defined roles of the notifications. The notification system allows an application to define in a secure manner users to roles. The notification system also allows the users to register in a secure manner their devices with the notification system. The notification system allows the application to then send a notification to users with a target role. Upon receiving the notification, the notification system identifies the devices of the users with the target role and sends the notification to those devices.

Abstract: Customizations, made at various levels in the customization channel, are saved as separate sets of customization deltas that are applied to a base computing system in order to generate a given solution. In a multi-tenant environment, groups of tenants access different solutions or customization deltas. The tenants are automatically grouped, based upon the solution or customization deltas that they access, and the deltas for those customizations are applied to the base system at runtime, for each group.

Abstract: A waste storage device is provided comprising a waste storage compartment for storing waste and a lid. The device further comprises a dispenser for dispensing an agent inside the waste storage device and an actuator arranged to activate the dispenser. A waste cartridge is also provided comprising a relatively rigid upper portion and a relatively flexible lower portion. The relatively flexible lower portion is arranged for storing waste items and the relatively rigid upper portion is arranged to be folded about an axis in a direction substantially towards the relatively flexible lower portion of the waste cartridge.

Abstract: A waste storage device (200) is provided comprising a waste storage compartment for storing waste and a lid (206). The device (200) further comprises a dispenser (208) for dispensing an agent inside the waste storage device (200) and an actuator (212) arranged to activate the dispenser (208).

Abstract: A ceiling fan cover that can be easily placed onto and removed from a ceiling fan to provide the fan from dust, wind, water, moisture, paint and other potentially harmful element. The cover can be constructed of a flexible or non-flexible material that contains opening and closing means that permit the cover to be placed onto and closed around said fan and then opened to remove the cover from the fan. The cover preferably is made of a material to permit its reuse.

Abstract: An energy meter which measures a volume of gas supplied, which measures a calorific value of the gas supplied, and which calculates an energy value corresponding to the measured volume of gas supplied and the calorific value. The structure to measure the volume of the gas supplied and to calculate the energy value may be provided in a single unit. The structure to measure the calorific value of the gas supplied preferably includes a structure to measure the speed of sound in the gas and further preferably measures a first thermal conductivity of the gas at a first temperature and measures a second thermal conductivity of the gas at a second temperature which differs from the first temperature, and is arranged to produce the calorific value of the gas corresponding to the measured speed of sound in the first and second thermal conductivities.
