Patrol vehicle communications system for users of both mobile and portable radios

Abstract

In a communications system for an individual who has access to a vehicle-mounted two-way radio and a portable two-way radio which includes a speakermic having a speaker through which audible messages are transmitted for the individual to hear, there is provided a volume control arrangement associated with the speakermic through which the audio volume of the speakermic speaker can be adjusted. The system also includes a transmitter for transmitting a signal to the volume control arrangement that the individual is seated in the vehicle, and further includes a transmitter for transmitting a signal to the volume control arrangement that the mobile radio is energized. A receiver is associated with the volume control arrangement of the speakermic so that upon receipt of the signals transmitted from the two transmitters, the audio volume of the speaker of the speakermic is automatically lowered.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) FIG. 1 is a perspective view of a communications system embodying features of the present invention and shown utilized in an exemplary environment of intended use.

(2) FIG. 2 is a view illustrating in block diagram form the operation of the communications system of FIG. 1.

DETAILED DESCRIPTION OF AN ILLUSTRATIVE EMBODIMENT

(3) Turning now to the drawings in greater detail and considering first FIG. 1, there is schematically illustrated an embodiment, generally indicated 20, of a communications system within which features of the present invention are embodied and shown utilized in an exemplary environment of intended use. The communications system 20 includes a vehicle-mounted mobile two-way radio system 22 whose components are mounted entirely within the body of a vehicle 18, and a portable two-way radio system 26 whose components are worn upon the person of an individual 30, such as a law enforcement officer, who is seated in the driver's seat, indicated 14, of the vehicle 18.

(4) As will be apparent herein, the communications system 20 includes componentry for sensing the presence of the individual 30 when the individual 30 is seated within the seat 14 of the vehicle 18 and componentry for sensing when the mobile radio 22 is energized (i.e. switched ON). This componentry, described herein, will automatically adjust (e.g. turn down) the volume of the portable radio system 26 when both the individual 30 is seated within the seat 14 and the mobile radio 22 is energized.

(5) The operation of the communications system 20 can be best understood with reference to the block diagram of FIG. 2. In particular, the communications system 20 includes a presence-sensing system 40 having a presence sensor 42 which is adapted to sense the presence of the individual 30 when seated within the seat 14 of the vehicle 18 and having an associated transmitter 44 for wirelessly transmitting a signal which corresponds to, or is indicative, of the fact (or event) that the individual 30 is seated within the seat 14. In other words, as long as the individual 30 is seated in the seat 14, a signal is generated by the sensor 42 that the individual 30 is, in fact, seated within the seat; and unless or until the individual 30 is present within the seat 14, no signal is generated by the sensor 42. The sensor 42 can take any of a number of forms, such as a plunger-operated switch 41 (FIG. 2) whose plunger is depressed (against the biasing force of a spring) when the individual 30 sits upon the seat 14, or the sensor 42 can take the form of a proximity sensor 46 (FIGS. 1 and 2) mounted within the headrest 12 (FIG. 1) of the seat 14 so that as soon as the individual 30 assumes a normal seating position within the seat 14, the sensor 42 senses the presence of the individual's head in front of the headrest 12 of the vehicle seat 14 and generates the corresponding (i.e. switching) signal for transmission (e.g. wirelessly) from the transmitter 44.

(6) The communications system 20 also includes a power sensing system 50 which is mounted adjacent the body, indicated 23, of the mobile radio 22 and which includes a power sensor 52 which is adapted to sense the energized (i.e. the switched ON) condition of the mobile radio 22 and an associated transmitter 56 for wirelessly transmitting a signal which corresponds to, or is indicative, of the fact (or event) that the mobile radio 22 is switched ON. In other words, as long as the power switch, indicated 25, of the mobile radio 22 is switched ON, a signal is generated by the sensor 52 (for transmission by the transmitter 56) that the mobile radio 22 is, in fact, switched ON; and unless or until the mobile radio 22 has been switched ON, no signal is generated by the power sensor 52. Although the power sensor 52 can take any of a number of forms, the sensor 52 of the depicted embodiment 20 is in the form of an two-position switch 54 which is wired to the power switch 25 of the mobile radio 22 for switching to a signalling mode during which a signal is generated indicative of the energized condition of the mobile radio 22 for transmission by the transmitter 56 to a site described herein.

(7) Meanwhile, there is associated with the portable radio 26 a speakermic 60 which is adapted to be worn on the lapel area of the clothing of the individual 30, and the speakermic 60 includes a microphone 66 and a speaker 62 through which messages which are transmitted to the portable radio 26 for the individual 30 to hear. Also associated with the portable radio 26 is a volume controller 64 through which the audio volume of the portable radio 26 is capable of being adjusted between raised and lowered volume levels.

(8) With reference again to FIGS. 1 and 2, the portable radio 26 includes a body 38 which is attached near the waist, or along the belt, of the individual 30. The major components and operating characteristics of the portable radio 26 are well-known so that a detailed description thereof is not believed to be necessary. Suffice it to say that the portable radio 26 is capable of being switched between a talk mode and a non-talk mode as an appropriate push-to-talk (PTT) switch is actuated.

(9) It is a feature of the communications system 20 that it includes a signal receiving system 70 which is mounted adjacent the speakermic 60 of the portable radio 26 and which includes a receiver 72 for receiving the signals which are (wirelessly) transmitted from both the presence-sensing sensor 42 and the power sensor 52. Operationally, the receiver 72 is adapted to receive the signals from the sensors 42 and 52 and generate a signal indicative that signals from both sensors 42 and 52 have been received. The receiver 72, in turn, is connected to the volume controller 64 of the speakermic 60 so that upon receipt of signals from both of the transmitters 44 and 56, the volume level of the speakermic 60 is lowered.

(10) It follows that the receiver 72 only sends an appropriate (volume-lowering) command signal to the volume controller 64 if signals from both of the presence-sensing sensor 42 and the power sensor 52 are received by the receiver 72. Thus, no (volume-lowering) command signal is sent from the receiver 72 to the volume controller 64 unless both the individual 30 is seated in the seat 14 and the power to the mobile radio 22 is switched ON (indicating that the both of the aforedescribed events are true).

(11) Upon cessation of the sending of any volume-lowering command signal from the receiver 72 to the volume controller (which would be indicative that either the individual 30 has moved out of his seat 14 or the power to the mobile radio 26 has been switched OFF, the volume level of the portable radio 26 reverts to its previous, or pre-set (e.g. original), level.

(12) It will be understood that numerous modifications and substitutions can be had to the aforedescribed embodiment 20 without departing from the spirit of the invention. Accordingly, the aforedescribed embodiment 20 is intended for the purpose of illustration and not as limitation.
