摘要:
A replaceable instrument mechanism for a haptic device comprises a coupler having a coupler body adapted to be connected to an output end of the haptic device. A force transmission mechanism is connected to the coupler body, has a movable connector displaceable along one degree-of-freedom with respect to the coupler body, and is connected to a force feedback system of the haptic device so as to receive force feedback from the haptic device and impart the force feedback to the movable connector. An instrument has an instrument body having a connector end releasably secured to the second end of the coupler body so as to be displaceable with the coupler. A handle portion is manually actuatable in one degree-of-freedom with respect to the instrument body to simulate an operation performed with the instrument. A member is associated with the handle portion so as to move by actuation of the handle portion, and releasably connected to the movable connector of the force transmission mechanism so as to transmit force feedback from the movable connector to the handle portion in response to actuation of the handle portion as detected by the haptic device.

A power supply system capable of providing electric power to an electronic device having a first battery includes a battery pack (100) and an attachment apparatus (300). The battery pack includes a body (110) having at least a first recess (221), a second battery inside the body, and at least one of a first circuit (500) capable of dynamically changing a charge current supplied to the second battery based on a power consumption level of the electronic device, and a second circuit (600) capable of dynamically switching the electronic device between a recharging state and a non-recharging state depending on a status of the battery pack. The attachment apparatus includes a frame (310), an extension (350) protruding from the frame, and attachment features (461) suitable for working with the recess to attach the battery pack and the attachment apparatus to each other and to the electronic device.

A holder, electrical supply, and optional radio frequency transmitter unit to hold, supply power to, and receive a data signal from an operating electronic device when the device (e.g., MP3 player) is held in the unit is disclosed. Electrical power enters the unit's power acquisition portion (e.g., cigarette lighter adapter) from an external source and flows to the electronic device via the holder. A data signal from the electronic device is processed by an radio frequency transmitter in the unit, and the resulting radio frequency signal is broadcast by an antenna (e.g., gooseneck) that preferably forms a repositionable mechanical connection between the holder and the power acquisition unit.

This invention is an improved distillation sequence for the separation and purification of ethylene from a cracked gas. A hydrocarbon feed enters a C2 distributor column. The top of the C2 distributor column is thermally coupled to an ethylene distributor column, and the bottoms liquid of a C2 distributor column feeds a deethanizer column. The C2 distributor column utilizes a conventional reboiler. The top of the ethylene distributor is thermally coupled with a demethanizer column, and the bottoms liquid of the ethylene distributor feeds a C2 splitter column. The ethylene distributor column utilizes a conventional reboiler. The deethanizer and C2 splitter columns are also thermally coupled and operated at a substantially lower pressure than the C2 distributor column, the ethylene distributor column, and the demethanizer column. Alternatively, a hydrocarbon feed enters a deethanizer column. The top of the deethanizer is thermally coupled to an ethylene distributor column, and the ethylene distributor column utilizes a conventional reboiler. The top of the ethylene distributor column is thermally coupled with a demethanizer column, and the bottoms liquid of the ethylene distributor column feeds a C2 splitter column. The C2 splitter column operates at a pressure substantially lower than the ethylene distributor column, the demethanizer column, and the deethanizer column.

In one embodiment, a rechargeable battery pack can be configured to power an electronic device having a first battery. The rechargeable battery pack can comprise a second battery supplemental to the first battery, an external power input configured to couple to an external power source, a power output for powering the electronic device. The rechargeable battery pack can also comprise a first circuit comprising a first power path between the external power input and the power output, a second power path between the second battery and the power output, and a power switch set. When the external power source is decoupled from the external power input, the first power path is disabled by the power switch set, and the second power path is enabled by the power switch set. When the external power source is coupled to the external power input, the first power path is enabled by the power switch set, and the second power path is disabled by the power switch set. Other examples and embodiments are described herein.

摘要:
A method of detecting oil aerosol in an air flow. The contaminated air is passed between an electrode (11) and an electrically conductive catalyst (14), and an electrical discharge therebetween causes electrostatic precipitation of oil on to the catalyst. Air flow and discharge are stopped, and the catalyst is heated with the air substantially stagnant until the catalytic combustion temperature of the oil is reached. The heat generation due to such combustion is sensed and used to produce an output signal indicative of the quantity of deposited oil.
