摘要:
The invention relates to a traditional closure means that can be actuated to open a container (10, 40, 70), which closure means comprises at least one actuation section (21, 50, 81) at which a user engages the closure means to perform an opening process and one closure section (22, 51, 83) operatively connected to the actuation section (21, 50, 81), which closure section closes the container and in which closure section the container is opened during the opening process, and with which closure section a fragrance is associated, wherein in order to avoid scent being released into the environment in an uncontrolled manner, it is proposed that a means for releasing the scent in a time-controlled manner be provided, which means is associated with the closure means, with which the activation of the release of the scent is performed in response to the performance of the opening process to open the container and which comprises a fragrance reservoir (30, 60, 90), which accommodates the fragrance, wherein the reservoir comprises a reservoir wall that can be broken open during the performance of the opening process. According to the invention, fragrance is applied to the actuation section (21, 50, 81).The invention further relates to a container (10, 40, 70) having such a closure means and to a method for opening such a container.

摘要:
A PFC circuit modulating a power line using pulse width modulation (PWM) to drive a power MOSFET and series inductor across the power line. Since many modern electronic systems include a power factor correction circuit (PFC) that already includes a series inductor and power MOSFET, a PLC is incorporated into a controller to inject a PLC transmit signal into a control loop for the PFC circuit. This can be done using either an analog PFC controller, such as the UCC28517, the UCC2819A, or a digital PFC controller such as based on a TMS32OC24xx DSP.
摘要:
A compact package for a garment made from a delicate material includes a container body having a volume of less than 10 in3 (164 cm3), a delicate material garment, a cover member and a cap. The cover member is inserted into the container body atop the garment, followed by the cap. Preferably, a buffer material is arranged between the garment and the cover member within the container body to protect the garment from damage during the packing process. The package is preferably produced by directing the garment and buffer material into a pre-loading tube, followed by shifting of a plunger member to load the container body with the garment, buffer material and the cover member. Subsequently, the cap is snap-fit upon the container body.
