Title: Wavelength division demultiplexing apparatus with branched connections
Inventor: TABUCHI HARUHIKO
IPC: G02B6/12
Filed: 2002-04-03
Abstract: Wavelength division demultiplexing apparatus, for example of the arrayed waveguide type, which can also be used for multiplexing, includes a first waveguide (1) for propagating wavelength division multiplexed light having wavelength components, a first slab (2) for diffusing the light from the first waveguide (1), channel waveguides (3) having a series of different waveguide lengths with a predetermined difference for receiving and propagating the light from the first slab (2). The apparatus also has a second slab (4) for receiving the wavelength division multiplexed light from the channel waveguides (3) and demultiplexing the received light into wavelength components with condensing each of the wavelength components, and a second waveguide (5) for propagating the light from the second slab (4), all formed on a based plate. The channel waveguides (3) and the first slab (2) are optically connected to each other at a number of nodes (24) greater than the number of nodes (44) at which the channel waveguides (3) and the second slab (4) are connected to each other. The output nodes (24) can then join together at junctions (69). There can also be several rows of junctions (see Fig 9) and the gap (G1, Fig 14) between nodes can be an island shaped formation of lower reflection index than the channel waveguides (3). Such apparatus can reduce the connection loss between an input slab and channel waveguides and suppress excitation of higher-order mode light to reduce the loss.

The resistive element may be a foil, a mesh, a ceramic material, and may have slits or apertures. The resistive element may be used to vaporise the medicament without pyrolysis. The resistive element may include a physical barrier to contain the medicament in a molten state. The resistive elements may be brought into engagement with a connector 34, and may be arranged on a carrier 35 such as a cassette reel. The resistive element may form part of a device 30 for vaporisation of the medicament, which may have a mouthpiece 43. The device may include means 32 to vary the duty cycle of the power supply to control the temperature and heating duration. The means 32 may also measure the resistive element and adjust the duty cycle depending on the measured resistance. The medicament may be cannabis extract.

Title: A method for monitoring the functionality of an electrochemical sensor for monitoring hydrogen concentration in a gas mixture
Inventor: KIESELE HERBERT
IPC: G01N27/416
Filed: 2003-04-10
Abstract: The invention relates to a method and a device for monitoring the hydrogen concentration in a gas with at least one device which comprises an electrochemical gas sensor and a bipotentiostat, for example for use in hydrogen-driven internal combustion engines, fuel cells and in petrochemistry. The electrochemical gas sensor used exhibits two working electrodes (3) and (4) with which the hydrogen and oxygen concentration in the gas is determined in different stages as a function of the voltage application by a bipotentiostat (5 -18). In a further optional stage a voltage ranging from -1100 to -800 millivolts is applied to a working electrode (4) so that hydrogen is formed on the working electrode (4), thus enabling the operable surface of the working electrode (4) and the sensitivity of the working electrode (3) to hydrogen to be tested. A cyclic repetition of the method stages, preferably staggered in time, with two devices, allows continuous monitoring of the hydrogen and oxygen concentration in regular testing of the working electrodes (3, 4) for their operability (Figure 1).

Title: A battery-operated grease gun with an electronic pressure regulator
Inventor: HUANG SAN-I
IPC: F16N11/08
Filed: 2003-05-30
Abstract: A battery operated grease gun has a motor (21) that drives a planetary gear assembly (30) that is coupled to a pump assembly that drives a plunger (45) reciprocally in an grease passage (413) to discharge grease through a discharge spout (43). The pressure in the grease exerts a reaction force on the plunger (45) that will change torque of the motor (21). The change of the torque of the motor (21) will simultaneously effect voltage applied to the motor (21). When the voltage in the motor (21) changes, an electronic pressure regulator measures the voltage in the motor (21) to determine the pressure in the grease passage and stops the motor (21) as the pressure in the grease passage reaches preset given values in the pressure regulating device.

IPC: G11B27/32
Filed: 2003-07-03
Abstract: A random number is generated which depends upon an initial value and the time taken to operate a command when playing a video game such as a quiz. A register 202 such as a GPRM register can be initialised by the RND function of an existing random number generator and is then set to a counter timer mode 204, a video sequence is retrieved 206 and played 208, a command button is activated 210 and the command invoked 214, before retrieving an playing the next sequence 216. If in a loop mode, and no button event occurrs 212 a value corresponding to the button is added to the register 222 before the next sequence is played. The generated random number may be used to control the video sequence, to select the next question of a quiz for instance. The video sequence may be recorded on a medium such as a DVD.

Title: Piston pump with leak prevention means for a fuel cell system
Inventor: SCHOFIELD NIGEL PAUL
IPC: F04B37/14
Filed: 2003-08-13
Abstract: A vacuum pump comprises at least one pumping chamber (80) defined by a bore (70), a reciprocating piston (68) housed in the bore and a first circumferentially extending sealing device (92). The piston (68) is provided with a second circumferentially extending sealing device (94) spaced apart from the first circumferentially extending sealing device (92) in a lengthways direction of the piston such than an annular chamber is defined in the space between the sealing devices. The pumping chamber (80) has an inlet port communicable with a pump inlet system (84, 85), an exhaust port communicable with a pump exhaust system and a scavenge port (98) communicating with the pump inlet system. The arrangement is such that the scavenge port (98) opens into the annular chamber such that when the piston reciprocates, in use, the first and second sealing devices (92, 94) do not pass the scavenge port (98). Fluid from the pumping chamber (80) that escapes past the first sealing device (90) is returned to the pump inlet system rather than passing the second sealing device (94) to the pump interior. The pump may be used in a fuel cell system comprising a fuel cell, a fuel reformer and a vacuum pump.

Title: Dual-track surface acoustic wave filter
Inventor: KIDOH HIDEO
IPC: H03H9/25
Filed: 2003-12-10
Abstract: A surface acoustic wave filter includes a first acoustic channel 3 which has first input/output transducers 3a,b and which is configured so as to define a first transfer function by the first input/output transducers, and a second acoustic channel 4 which has second input/output transducers 4a,b and which is configured so as to define a second transfer function by the second input/output transducers. The first and second acoustic channels are electrically connected in parallel. The first and second transfer functions are substantially in phase within a pass band, while they have substantially opposite phases outside the pass band. The bandwidth of the second acoustic channel is narrower than that of the first acoustic channel. A first side lobe of the second transfer function has a phase opposite to that of a main lobe of the first acoustic channel. This arrangement is stated to steepen the filter characteristic, and so suppress out-of-band response.
