Abstract: Systems and methods of receiving voice input are disclosed herein. In one embodiment, for example, a network microphone device is configured to cause an output of a feedback element only if received voice input data comprises the valid wake word. In another embodiment, for example, a network microphone device is configured to determine a type of command request in voice input data, and cause output of a feedback element corresponding to the determined type of command request. In one embodiment, for example, a media playback system is configured to play back media content via first and second playback devices, and further configured to cause output, via the second playback device, of a feedback element corresponding to voice input received at the second playback device.

Abstract: Example techniques relate to device spaces and default designations in a media playback system. A device space may create an association between a networked microphone device and one or more playback devices such that certain voice commands (e.g., playback commands) received by the networked microphone device are used to control the one or more playback devices (unless otherwise designated in the voice command). Furthermore, in bonded pairs and bonded groups of playback devices that include at least one NMD, certain playback devices within the bonded pair or group may be designated as default so as to avoid multiple responses to a voice input.

Abstract: A method for controlling a heated process of an electric heater includes obtaining a setpoint variable indicating a target temperature of the heater. The method includes identifying an energy profile for the heater based on the setpoint variable. The energy profile provides a defined magnitude of initial electrical energy to be applied to the heater to have a temperature of the heated process reach the target temperature. The method includes obtaining a process variable indicating a performance characteristic of the heated process. The method includes providing electrical energy to the heater based on at least one of the energy profile and the process variable.

Abstract: A mould for the production of a contact lens, the mould comprising a first mould half shaped to provide the front surface of the contact lens; and a second mould half shaped to provide the rear surface of the contact lens, wherein the first and second mould halves form a mould cavity, wherein the first mould half has a first rim and the second mould half has a second rim, and the first and second rims fit together to provide a seal for the mould cavity, wherein the first rim is inclined at an angle of x relative to an axis passing through the centre of the first and second mould halves, wherein x is from 30 to 60°, and wherein the second rim is inclined at an angle of x-y relative to the axis passing through the centre of the first and second mould halves, where y is from 0 to 4°, and wherein the first and second rims provide a guide for the mould halves, a method of making a contact lens using the mould and a method of making a mould.

Abstract: A fluid composition for producing a gold seed layer on a substrate for an electrical circuit, which comprises an organogold and an organosliver compound present as 0.5 to 10 parts by weight silver per 100 parts by weight gold. In preferred compositions the silver is present as 0.8 to 6 parts by weight per 100 parts gold. The process improves seed layer to substrate adhesion.

Abstract: Polyamides containing in-chain aromatic groups, particularly diphenyl groups. Such polyamides may be prepared by reacting an alpha-omega-hydrocarbyl bis(biphenyl-2,2.sup.1 -dicarboxylmide) with a diamine and are useful as the matrix in fibre-reinforced composites.
