Patent GB-201216093-D0 (GB)
Title: Apparatus for testing hearing
Filed: 2012-09-10
Abstract: Apparatus for testing hearing 100 is arranged to transmit audio tones over the Internet 125 to be output at a receiving station 105, 120 such as a user's computer. The apparatus includes an audio tone store (245, fig. 2) storing each audio tone as a set of two or more components, each component having the same frequency but recorded at different modulation levels. This allows significantly finer control over the sound level of the audio tones at the receiving station than would normally be available at the receiving end. The apparatus also calibrates of the volume of the audible output of the receiving station. A feedback loop is provided where a calibrated audio tone is delivered for output at the receiving station 105, 120 and is transmitted as audible sound back to the hearing test apparatus. The apparatus sends display data to the receiving station representing the sound level of that audible sound, so that a user can adjust the volume of the audible sound at the receiving station to a calibrated level using the display. Alternatively, the apparatus may adjust the receiving station directly, using a Java applet or the like. Calibration can additionally or instead be provided by means of an audio pickup (e.g. a microphone) for measuring and feeding back the level of audio output at user audio delivery equipment (e.g. headphones 115, 110) .
Patent GB-201223498-D0 (GB)
Title: Thatch fixing method
Filed: 2012-12-30
Abstract: This invention relates to a fixing device for attaching the first layer of thatch material to a roof structure. It consists of two separate components; a head which has a hole and a downward curved hook and a long screw with a wide head. The screw may have an inch thread. The screw is inserted into the hole in the separate head. The curve hook of the head provides a means for holding a bar in place over the thatch material and the screw provides a secure fixing point to the roof. The use of a screw causes less damage to roof structures than traditional fixing methods. It is designed to be used in conjunction with hazel bar, which overcomes the issues posed by modern fixing methods. It enables the thatch to be stripped off quickly in the event of a fire, unlike modern methods that use metal and wire.

Title: Buffer device used in a voice transmission network
Inventor: PLATEL GUY
IPC: H04L12/64
Filed: 1984-05-23
Granted: 1988-12-15
Abstract: Packets input to a buffer register (10) increment the contents of two counters (12,20). At 40ms intervals a real-time clock resets one counter (12) to zero after transferring its contents to a logic circuit (14) which addresses a memory (16). One output from the memory defines the buffer content (L), monitored by the other counter (20), at which the oldest packets in the buffer are suppressed by a cancelling device (22). Another output from the memory stipulates the number (x) of old packets which are to be suppressed. The real-time clock may be replaced by a comparator comparing the buffer output packet count with a fixed quantity.
