Creating, confirming, and managing employee schedules

A system and method for creating, confirming and managing employee schedules comprises creating a schedule having time slots comprising shifts having employees, publishing the schedule on a network to the employees, and receiving a response of a confirmation, a request for shift change, and a null response from each employee. For each employee, if a null response is received, a reminder is sent. If request for shift change is received, an alert is sent to eligible employees using a preferred communication mode, and if one of the eligible employees responds, the shift change may be confirmed automatically or with manager approval. If approved, the employee requesting the change and the eligible employee are notified of the change; if not approved, both employees are notified of the lack of change. The schedule can be published using an employee's preferred communication mode. All steps contain implications for the system's three-step color-coding schema.

Passive doppler fuze

A passive proximity fuze. The inventive fuze (10) is adapted to be mounted on a munition (11) and includes a receiver (16) adapted to lock on to a signal transmitted by a target transmitter (12). The receiver (16) detects a Doppler shift in the signal as the munition approaches the target. When a closest point of approach is reached the Doppler shift changes from increasing to decreasing. The inventive fuze (10) includes a mechanism for detecting this change in the Doppler shift and provides a detonation signal in response thereto. In the illustrative embodiment, the receiver (16) is an FM receiver. The mechanism for detecting a change in the Doppler shift may be implemented with discrete analog circuitry or digital circuitry. In an illustrative analog implementation, first and second resistive / capacitive networks (R1C1 and R2C2) are employed to compute a second derivative of the Doppler shift signal output by the receiver (16). This signal is then amplified and thresholded to provide the output detonation signal. In an illustrative digital implementation, the output of the receiver (16) is converted to digital and processed by a digital signal processor (26). The DSP 26 computes the second derivative of the Doppler shift signal output by the receiver (16) in response to a stored program for computing same. The output of the DSP is the detonation signal. Hence, detonation is achieved at the closest point of approach of the munition (11) to the target (12) with an inexpensive passive solution (10).

Optical modulator

In a nest MZI modulator in which each arm includes a child MZI, the power consumption is reduced. The hybrid integrated-type nest MZI modulator of the embodiment 1a is configured so that, instead of placing a relative phase adjusting section in a parent MZI, a bias electrode Bias 90° in which an electric field is applied in the same direction to the polarization direction in both of the upper and lower arms is placed in each child MZI (see FIG. 4B). The bias electrode Bias 90° provided in each child MZI constitute the entirety of a relative phase adjusting section. The optical signals are subjected to a phase change after the output from the child MZI (see FIG. 1A), because such relative phase adjusting section can subject the optical signals of the upper and lower arms of the child MZI to a shift change in the same direction, respectively.

Sound effect producing apparatus for vehicle

ActiveUS20070223727A1Natural sound effectGain can be increasedGain controlTransmissionDriver/operatorControl signal
A processor determines an engagement state of a clutch based on a clutch signal, which is output from a clutch switch connected to a clutch pedal. In a declutching state, the processor lowers weighting gain characteristics that serve as acoustic correcting characteristics used in a sound pressure adjuster. Therefore, even when a change of an engine rotational frequency per unit of time increases during a shift-change operation, the gain of the control signal is prevented from increasing. Accordingly, a gap between real acceleration of the vehicle and a sound effect output from a speaker can be decreased, thereby reducing the possibility that the driver and / or a passenger in the vehicle may feel a sense of strangeness relative to the sound effect.

Antenna system for sharing of operation

An antenna system for sharing of operation employs contiguous transmit frequencies. Transmit frequencies are separated into non-contiguous sub-groups isolated from one another by filters 158(+) and 160(−) associated with positive and negative polarization. Received frequencies are filtered and split into five signals for input to base station receive ports. Non-contiguous transmit frequency sub-groups are combined by a quadrature hybrid 110 and pass with 90 degree relative phase shift to mutually orthogonal antenna stack ports P(+) and P(−) associated with orthogonally polarized sets of antenna elements AS(+) and AS(−): the ports P(+) and P(−) are isolated from one another by the hybrid 110. The 90 degree phase shift results in one transmit subgroup being radiated with left hand circular polarization and the other transmit subgroup being radiated with right hand circular polarization. Changing the relative phase shift changes the radiated polarization to linear or elliptical, and signal amplitude weighting provides control of antenna beam polarization direction.
