Title: An error amplifier
Inventor: LAURENCE REID
IPC: H03H11/12
Filed: 2017-08-07
Abstract: Error amplifier 40 for a pulse width modulation (PWM) circuit which includes an operational amplifier (op-amp 50) configured as an integrator and a feedback loop coupled between operational amplifier signal output 48 and inverting (-) input. The feedback loop comprises a feedback capacitor 54 coupled to signal output 48, a feedback resistor 56 coupled to the feedback capacitor, and an integrator resistor 58 coupled to feedback resistor 56 and op-amp inverting input. Junction between feedback and integrator resistors is configured to receive an input signal (via 42) whilst junction between feedback resistor and capacitor is configured to receive a feedback signal from the PWM circuit (via 46). The feedback capacitor may compensate for excess phase shift at switching frequency whilst the integration function may be separated from feedback summing function. The PWM signal may attenuate a modulation component by a series connected low pass filter LPF (e.g “T”-filter resistors 62,66 shunt capacitor 64) prior to passing signal to feedback capacitor/resistor node. A second low pass filter (pi-filter shunt capacitors 72,74, series resistors 76,60 fig-3) between signal input and feedback/integrator resistor junction attenuates aliasing frequency components (anti-alias filter). A feedforward capacitor 52 is preferably connected between operational amplifier inverting and output nodes. Also included is a PWM circuit comprising the error amplifier coupled to a driver (e.g PWM driver) which provides a modulated signal to drive switching device(s) (e.g in push-pull 22, 20) and switching device output forms the error amplifier feedback signal, and wherein the operational amplifier signal output is coupled to the driver circuit. The PWM circuit may couple to an audio loudspeaker or a motor (figs 5-6).

Title: Bicycle derailleur
Inventor: CHANG-YAO YANG
IPC: B62M9/16
Filed: 2018-08-06
Abstract: A bicycle derailleur comprises a chain tensioning arrangement including an external chain guiding member 11 and a pivot 30. A C-shaped spring 50 encircles the pivot 30 and has two ends, 52, 53. The first end 52 is located securely while the second end 53 may move. Movement of the guide member 11 to slacken a chain (D1) causes rotation of pivot 30 relative to C-shaped spring 50, and friction therebetween causes the end 53 of spring 50 to move towards end 52, tightening spring 50 onto the pivot 30 increasing damping friction. Conversely, rotation of the guide member 11 to tighten the chain (D2) causes pivot 30 to rotate against spring 50 moving end 53 away from end 52, relaxing the spring 50 on pivot 30 and reducing damping friction. In this way, the derailleur provides a greater damping force to resist slackening of the chain than to tensioning of the chain. A switch shaft 60 may be provided to de-activate the C-shaped spring by holding ends 52, 53 apart (Figure 2B), disengaging them from the pivot 30.
