Abstract: A recipe is stored on a recipe framework. A user has one or more devices and one or more appliances. A recipe program presents recipe information using a device interface on a first device and/or on an appliance interface of a first appliance. The device or appliance interfaces track user interactions with the recipe program. A version of the recipe's progress and state is maintained in said framework. While the recipe is in progress, and in response to the user switching to a second device and/or appliance, presenting recipe information on the second device and/or appliance based on the version of the progress and state of the recipe maintained in the recipe framework. The second device or second appliance obtains the version of the progress and state from the recipe framework. The device and appliance user interfaces present a consistent and contextual view of the state of the recipe.

Abstract: A switching circuit (20) comprising first and second switch terminals (2,3) and a switch (21). The switch (21) comprises a first bipolar transistor (22), having a collector connected to the first switch terminal (2) and an emitter connected to the second switch terminal (3), and a second bipolar transistor (23), having an emitter connected to the first switch terminal (2) and a collector connected to the second switch terminal (3). The switch (21) can be turned on by supply of a control current to the base of either the first or the second bipolar transistor.
