摘要： In various example embodiments, a low energy electric motor brake is described comprising one or more electronic switches that connect the input wires to an electric motor together, thus shorting out the motor and braking the motor. The electronic switches are separate from the control system, and provide the braking function. This alleviates the motor controllers and other system control units from providing the braking function to the motor. The electronic switches require minimal to no power in order to maintain the brake to the motor. The control unit may be placed in a low power or sleep mode while the electronic switches maintain the brake.

摘要： Disclosed herein are wireless devices operable at intermediate wireless at ranges of thousands of meters, utilizing packets that include a preamble and a data payload. Devices may be such things as keypads, door latches, occupancy monitors, sprinkler controllers and other devices needing a communications link. A digital spread-spectrum frequency hopping rotation is used, wherein packet transmissions rotate through frequency sequences. A spectrum-impact-smoothed channel set is fashioned using sequences that each specify a unique preamble frequency relative to the other sequences and channels. The set is traversed as packets are transmitted, thereby distributing the focused radio-frequency emission impact of packets having long preambles over time. Packet acknowledgments are deferred until a group of packets in a stream has been exchanged. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.

摘要： Embodiments of a parking brake and anti-theft apparatus for a vented disc brake system are described herein. Such embodiments may include a brake assembly, an actuator and a rocker or a locking arm. The brake assembly by include a first and second rotor plates separated by spacers and slots. The rocker and locking arm may include pawls extending from an edge, and may be positioned adjacent to a circumference of the rotor plates, aligned between the rotor plates. The actuator may move the rocker and/or locking arm between locked an unlocked positions such that, in the locked configuration, the pawls are inserted into the slots, and in the unlocked configuration, the pawls are disposed outside the slots.

摘要： We disclose a method of using taggants to assess how and to what extent a drug in a drug composition that a user has consumed has decayed in response to storage conditions and time. The taggants may decay in response to environmental conditions which cause different drugs to lose their efficacy. These environmental conditions may include light, temperature, oxidation, moisture, and age. The taggants may be detected in biological samples, including urine and feces. By identifying the taggants, the drug composition and other information relating to the drug may be identified. Additionally, quantification of the different taggants may be used to determine whether the drug in the drug composition has been exposed to environmental conditions which may reduce its efficacy.

摘要： A gear-shifting device is disclosed. The device comprises a first motor having a first stator. The first stator turns clockwise and counter-clockwise, creating a wobbling action. The device further comprises a compound planetary transmission, comprising a transmission ring attached to a ring gear. The compound planetary transmission receives power from the first stator. The device further comprises a second motor having a second stator. The second stator turns clockwise and counter-clockwise. The device further comprises a shift assembly, comprising a drum, a cap, and a pinion gear. The pinion gear receives power from the second stator. The drum locks with the pinion gear such that the drum rotates with the pinion gear. The transmission ring is attached to the drum, such that the transmission ring moves laterally as the drum rotates. The ring gear locks and unlocks with the cap as the drum rotates. The wobbling action enables the locking.

摘要： Various embodiments of an apparatus for changing the in-air pitch and/or roll of a land craft are described herein. The apparatus may include a steering input mechanism, a support structure, and an articulator. The apparatus may include one or more of a pitch-forward input mechanism, a pitch-back input mechanism, a roll-right input mechanism, and a roll-left input mechanism. The vehicle may include a set of wheels on which the vehicle travels over ground. The steering input mechanism may receive steering inputs from a driver of the vehicle. The steering input mechanism may receive pitch and roll control inputs from the driver. The support structure may connect the steering input mechanism to the vehicle, at least one of the wheels, or the vehicle and the at least one of the wheels. The articulator may rotatably connect the steering input mechanism to the support structure.

摘要： The tandem differential mobility spectrometer (DMS)-ion modulator instrument provides improved resolution relative to traditional DMS for molecules with larger masses. The instrument includes an ion-bunching electrode with an AC field synchronized to the transit time of the ion flow which is positioned downstream of a DMS. The ion bunching electrode produces a mobility-dependent modulation of the ion current. The ratio of AC to DC current provides a measure of the mobility of a large ion, even if it has little differential mobility, thereby extending the useful range of mobility characterization of a DMS system. The instrument is more compact than a larger traditional ion mobility spectrometer and does not require high voltages or high frequencies. Modulation before DMS separation or between tandem DMS separations produces a variable range of analyte and reactant ion densities as well as spatially separating negative and positive ions to reduce ion recombination.

摘要： A window shade alarm system for gently awakening a user. The window shade is connected to the Internet and opens such that light gradually increases in a room. Thus waking a user less abruptly than a traditional audio alarm. The window shade stores user selected modes and can control wireless enabled lights within a room to simulate the gradual increase of light at sunrise. The alarm system is connected to remote activated devices for the convenience of the user.
