Patent Application
20100090853
The present invention relates to a visual-protective warning apparatus and more particularly to a visual-protective warning apparatus that activates an alarm when an object is too close to a person's eyes.
According to market analysis projections of the Market Intelligence Center (MIC) of the Institute for Information Industry in Taiwan, people will spend more than ten billion New Taiwan dollars or roughly three hundred million US dollars playing online games in 2008. The market is projected to grow to 12 billion New Taiwan dollars or more than 360 million US dollars in 2010, and the largest group of people includes not only students but also white-collar workers.
However, online game business is only a part of online business. Other services that also attract many people include blogs, chat rooms, and electronic albums. People accessing online services often spend many consecutive hours reading other people's diaries or stories or looking at photos, which may result in a person getting too close to a computer screen, printed material or an object that needs to be perused or studied closely and suffering from eye strain or posture related disorders.
Therefore, an invention is needed that will reduce the likelihood of damage to a person's eyes and promote good posture.
The objective of a visual-protective warning apparatus in accordance with the present invention is to reduce the likelihood of damage to a person's eyes and promote good posture.
A visual-protective warning apparatus in accordance with the present invention that prevents the distance between a person's eyes and a visual object being too close to each other comprises a transmitter and a receiver. The transmitter is mounted on a person and transmits a wireless signal. The receiver has a warning indicator that is activated when RSSI of the wireless signal from the transmitter exceeds a threshold.
A visual-protective warning apparatus in accordance with present invention comprises an indicator, at least one wireless module and a power module.
With reference to
The transmitter (11) is a wireless module, may be an MSP430 microcontroller, is worn on a person's (13) forehead, transmits a wireless signal (112) that may be an IEEE 802.15.4/ZigBee protocol and has a power module (111).
The power module (111) provides DC power to operate the transmitter (11) and comprises a battery assembly, an optional USB plug and an optional AC assembly.
The battery assembly is mounted in the transmitter (11) and comprises a battery compartment and at least one battery. The battery compartment is formed inside the transmitter (11).
The batteries are mounted removably in the battery compartment and provide DC power to operate the transmitter (11).
The USB plug extends through the transmitter (11) and provides DC power to drive the transmitter (11) when plugged into an active USB connector such as a USB connector on an operating computer (15).
The AC assembly comprises a rectifier and an electric cord. The rectifier is mounted in the transmitter (11), converts AC to DC power and provides DC power to drive the transmitter (11).
The electric cord connects to the rectifier, extends from the transmitter (11) and selectively connects to an external AC power source.
The receiver (10) is a wireless module, may be an MSP430 microcontroller, is mounted on a book (12), other printed material, a monitor (151) or any object, senses a received signal strength indication (RSSI) of the wireless signal (112) from the transmitter (11), determines how far the transmitter (11) is from the receiver (10) based on RSSI and comprises a warning indicator (101) and a power module (102).
The warning indicator (101) is mounted in the receiver (10), provides a warning indication when the person (13) wearing the transmitter (11) is close enough to the receiver (10) to cause the RSSI to exceed a threshold such as an RSSI greater than 200 and may be a vibrator, a light, a buzzer or a speaker.
The power module (102) provides DC power to operate the receiver (10) and the warning indicator (101) and comprises a battery assembly, an optional USB plug and an optional AC assembly.
The battery assembly is mounted in the receiver (10), is connected to the warning indicator (101) and comprises a battery compartment and at least one battery.
The battery compartment is formed inside the receiver (10).
The batteries are mounted removably in the battery compartment and provide DC power to operate the receiver (10) and the indicator (101).
The USB plug extends through the receiver (10) and provides DC power to drive the receiver (10) and the warning indicator (101) when plugged into an active USB connector such as a USB connector on an operating computer (15).
The AC assembly comprises a rectifier and an electric cord. The rectifier is mounted in the receiver (10), converts AC to DC power, is connected to the warning indicator (101) and provides DC power to drive the receiver (10) and the warning indicator (101).
The electric cord connects to the rectifier, extends from the receiver (10) and selectively connects to an external AC power source.
People skilled in the art will understand that various changes, modifications and alterations in form and details may be made without departing from the spirit and scope of the invention.
