    • The invention concerns a method (300) of providing information about a communications device. The method includes the steps of establishing (312) a communications connection between a first mobile communications unit (128) and at least a second mobile communications unit (130), transmitting (314) from the first mobile communications unit to the second mobile communications unit a condition of at least one operational parameter of the first mobile communications unit and informing (316) a user of the second mobile communications unit of the conditions of the operational parameters of the first mobile communications unit. The operational parameters of the first mobile communications unit can include a signal strength, a battery level, a location, an audio configuration, an alert configuration, a conference indicator and a phone type indicator.

    • A device (50) capable of selectively altering its appearance can include a housing portion (64) of the device having at least one photochromic compound and an ultraviolet light source (60) forming a portion of the device for exposing the portion of the device having the photochromic compound to the ultraviolet light source. A reaction by the photochromic compound can provide or serve as a status indicator for the device. The device can be any number of devices such as a portable communication device, a personal digital assistant, a laptop computer, a camera, a GPS device, a printer, a camcorder, a vehicle, a toy, a personal hygiene device, a watch, a calculator, and a writing instrument for example. The device can be formed so that reactions by the photochromic compounds within the device are controlled solely by the ultraviolet light sources (54 and 60) within the device.

    • A communication system (100) provides for improved dispatch communications, by providing a method for monitoring the signal quality at each of the Mobile Stations (MS) involved in a dispatch call. Once engaged in the dispatch call, the MSs (110, 112) monitor the signal quality of their ACCH channel (204) and send a message back to the system (208) if their signal quality falls below a predetermined threshold. If the signal quality of any dispatch call participant falls below the given threshold (206), the system alerts all the dispatch call participants (210) thereby avoiding any loss of communications, and tears down the previously set up dispatch call. If the signal quality becomes acceptable again (216) for those MS who had previously experienced poor signal quality, they send a message to the system, which automatically sets up a new dispatch call and alerts all the dispatch participants that the dispatch channel can be used again (218).
    • 通信系统(100)通过提供一种用于监视在调度呼叫中涉及的每个移动站(MS)处的信号质量的方法来提供改进的调度通信。 一旦进入调度呼叫,MS(110,112)监视其ACCH信道(204)的信号质量,并且如果信号质量低于预定阈值则将消息发送回系统(208)。 如果任何调度呼叫参与者的信号质量低于给定阈值(206),则系统警告所有调度呼叫参与者(210),从而避免任何通信丢失,并撕下先前设置的调度呼叫。 如果先前信号质量差的那些信号质量再次可以接受(216),那么它们会向系统发送消息,该消息会自动建立新的调度呼叫,并向所有调度参与者通知所有调度信道都可以使用 再次(218)。
